Summary of Significant Accounting Policies (Policies)	6 Months Ended
Summary of Significant Accounting Policies (Policies)	Sep. 30, 2017
Accounting Policies [Abstract]
Consolidation	The interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. The interim consolidated financial statements as of September 30, 2017 and for the three and six months ended September 30, 2017 and October 1, 2016 are unaudited. In addition, certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. The interim consolidated financial statements reflect all normal and recurring adjustments, which are, in the opinion of management, necessary for a fair presentation in conformity with U.S. GAAP. The interim consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto for the year ended April 1, 2017, as filed with the Securities and Exchange Commission on May 31, 2017, in the Company’s Annual Report on Form 10-K. The results of operations for the interim periods should not be considered indicative of results to be expected for the full fiscal year.
Fiscal Period	The Company utilizes a 52 to 53 week fiscal year ending on the Saturday closest to March 31. As such, the term “Fiscal Year” or “Fiscal” refers to the 52-week or 53-week period, ending on that day. The results for the three and six months ended September 30, 2017 and October 1, 2016, are based on 13-week and 26-week periods, respectively.
Use of Estimates	The preparation of financial statements in accordance with U.S. GAAP requires management to use judgment and make estimates that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The level of uncertainty in estimates and assumptions increases with the length of time until the underlying transactions are completed. The most significant assumptions and estimates involved in preparing the consolidated financial statements include allowances for customer deductions, sales returns, sales discounts and doubtful accounts, estimates of inventory recovery, the valuation of share-based compensation, valuation of deferred taxes and the estimated useful lives used for amortization and depreciation of intangible assets and property and equipment. Actual results could differ from those estimates.
Reclassifications	Certain reclassifications have been made to the prior periods’ financial information in order to conform to the current period’s presentation.
Seasonality	The Company experiences certain effects of seasonality with respect to its wholesale and retail segments. The Company’s wholesale segment generally experiences its lowest sales in its first fiscal quarter. The Company’s retail segment generally experiences greater sales during its third fiscal quarter as a result of holiday season sales. In the aggregate, the Company’s first fiscal quarter typically experiences significantly less sales volume relative to the other three quarters and its third fiscal quarter generally has higher sales volume relative to the other three quarters.
Derivative Financial Instruments	The Company uses forward currency exchange contracts to manage its exposure to fluctuations in foreign currency for certain transactions. The Company, in its normal course of business, enters into transactions with foreign suppliers and seeks to minimize risks related to these transactions. The Company employs these forward currency contracts to hedge the Company’s cash flows, as they relate to foreign currency transactions. Certain of these contracts are designated as hedges for accounting purposes, while others remain undesignated. All of the Company’s derivative instruments are recorded in the Company’s consolidated balance sheets at fair value on a gross basis, regardless of their hedge designation. In connection with the July 25, 2017 recommended cash offer for the entire issued and to be issued share capital of Jimmy Choo PLC, a public company organized under the laws of England and Wales and its subsidiaries (collectively, "Jimmy Choo"), the Company entered into a forward foreign currency exchange contract with a notional amount of £1.115 billion to mitigate its foreign currency exchange risk through the expected closing date of the acquisition. This derivative contract was not designated as an accounting hedge. Therefore, changes in fair value are recorded to foreign currency (gain) loss in the Company's consolidated statement of operations. The Company’s accounting policy is to classify cash flows from derivative instruments that are accounted for as cash flow hedges in the same category as the cash flows from the items being hedged. Accordingly, the Company classified the unrealized gain relating to this derivative instrument within cash flows from investing activities. The Company designates certain contracts related to the purchase of inventory that qualify for hedge accounting as cash flow hedges. Formal hedge documentation is prepared for all derivative instruments designated as hedges, including description of the hedged item and the hedging instrument, the risk being hedged, and the manner in which hedge effectiveness will be assessed prospectively and retrospectively. The effective portion of changes in the fair value for contracts designated as cash flow hedges is recorded in equity as a component of accumulated other comprehensive income (loss) until the hedged item effects earnings. When the inventory related to forecasted inventory purchases that are being hedged is sold to a third party, the gains or losses deferred in accumulated other comprehensive income (loss) are recognized within cost of goods sold. The Company uses regression analysis to assess effectiveness of derivative instruments that are designated as hedges, which compares the change in the fair value of the derivative instrument to the change in the related hedged item. Effectiveness is assessed on a quarterly basis and any portion of the designated hedge contracts deemed ineffective is recorded to foreign currency gain (loss). If the hedge is no longer expected to be highly effective in the future, future changes in the fair value are recognized in earnings. For those contracts that are not designated as hedges, changes in the fair value are recorded to foreign currency gain (loss) in the Company’s consolidated statements of operations and comprehensive income. The Company classifies cash flows relating to its derivative instruments consistently with the classification of the hedged item, or within operating activities for contracts related to inventory purchases. The Company is exposed to the risk that counterparties to derivative contracts will fail to meet their contractual obligations. In order to mitigate counterparty credit risk, the Company only enters into contracts with carefully selected financial institutions based upon their credit ratings and certain other financial factors, adhering to established limits for credit exposure. The aforementioned forward contracts generally have a term of no more than 12 months. The period of these contracts is directly related to the foreign transaction they are intended to hedge.
Net Income per Share	The Company’s basic net income per ordinary share is calculated by dividing net income by the weighted average number of ordinary shares outstanding during the period. Diluted net income per ordinary share reflects the potential dilution that would occur if share option grants or any other potentially dilutive instruments, including restricted shares and units (“RSUs”), were exercised or converted into ordinary shares. These potentially dilutive securities are included in diluted shares to the extent they are dilutive under the treasury stock method for the applicable periods. Performance-based RSUs are included in diluted shares if the related performance conditions are considered satisfied as of the end of the reporting period and to the extent they are dilutive under the treasury stock method.
Recently Adopted and Issued Accounting Pronouncements	Recently Adopted Accounting Pronouncements Share-Based Compensation In March 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-09, "Improvements to Employee Share-Based Payment Accounting," which simplifies accounting and presentation of share-based payments, primarily relating to the recognition and classification of excess tax benefits, accounting for forfeitures and tax withholding requirements. The Company adopted ASU 2016-09 during the first quarter of Fiscal 2018, as required. Accordingly, during the three and six months ended September 30, 2017, excess tax benefits of $5.0 million and $0.1 million, respectively, which would have been previously reflected within additional paid-in capital, were recognized within the Company's provision of income taxes. This change is expected to increase volatility in future provisions for income taxes. In addition, the Company eliminated windfall tax benefits from the treasury stock method calculation used to compute its diluted earnings per share. Both of the above changes have been adopted on a prospective basis, whereas cash flows related to excess tax benefits, previously reflected within financing activities, have been presented within operating activities within the Company's consolidated statements of cash flows on a retrospective basis. Cash flows related to excess tax benefits were $2.8 million during the six months ended October 1, 2016. The Company continues to reflect estimated forfeitures in its share-based compensation expense. Recently Issued Accounting Pronouncements We have considered all new accounting pronouncements and, other than the recent pronouncements discussed below, have concluded that there are no new pronouncements that may have a material impact on our results of operations, financial condition or cash flows based on current information. Hedge Accounting On August 28, 2017, the FASB issued ASU No. 2017-12, "Targeted Improvements to Accounting for Hedging Activities." The new standard is intended to improve and simplify rules relating to hedge accounting, including the elimination of periodic hedge ineffectiveness, recognition and presentation of components excluded from hedge effectiveness assessment, the ability to elect to perform subsequent effectiveness assessments qualitatively, and other provisions designed to provide more transparency around the economics of a company's hedging strategy. ASU 2017-12 is effective for the Company in Fiscal 2020, with early adoption permitted. The Company is currently evaluating the impact of ASU 2017-12 on its consolidated financial statements. Revenue Recognition In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers,” which provides new guidance for revenues recognized from contracts with customers, and will replace the existing revenue recognition guidance. ASU 2014-09 requires that revenue is recognized at an amount the company is entitled to upon transferring control of goods or services to customers, as opposed to when risks and rewards transfer to a customer. In July 2015, the FASB issued ASU No. 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date," which deferred the effective date of ASU 2014-09 by one year, making it effective for the interim reporting periods within the annual reporting period beginning after December 15, 2017, or beginning with the Company’s Fiscal 2019. This standard may be applied retrospectively to all prior periods presented, or retrospectively with a cumulative adjustment to retained earnings in the year of adoption. The FASB has issued several additional ASUs to provide implementation guidance on ASU No. 2014-09, including ASU No. 2016-20, "Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers" issued in December 2016, ASU No. 2016-12, "Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients" issued in May 2016, ASU No. 2016-10, "Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing" issued in April 2016, and ASU No. 2016-08, "Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net)" issued in March 2016 . The Company will consider this guidance in evaluating the impact of ASU 2014-09. Most of our business is comprised of retail and wholesale operations, where revenue is recognized at a point of time. The Company has completed the initial assessment of the new standard and is currently progressing in its implementation. While the evaluation process is not complete, based on our assessment to date, the Company believes that some of the potential impacts of implementing this standard will include the timing of revenue recognition for its licensing royalties, recognition of breakage revenue for unredeemed gift cards, as well as expanded financial statement disclosures, including revenue recognition policies to identify performance obligations to customers and significant judgments in measurement and recognition. The Company currently anticipates adopting this standard using the modified retrospective method with the cumulative adjustment to retained earnings recorded during the first quarter of Fiscal 2019. Lease Accounting In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)," which requires lessees to recognize a lease liability and a right-to-use asset on the balance sheet for all leases, except certain short-term leases. ASU 2016-02 is effective beginning with the Company's Fiscal 2020, with early adoption permitted, and must be implemented using a modified retrospective approach for all leases existing at, or entered into after the beginning of the earliest comparative period that is presented in the financial statements. The Company is currently evaluating the impact of ASU 2016-02 on its consolidated financial statements but expects that the adoption of this standard will result in a significant increase in assets and liabilities on its consolidated balance sheets. Goodwill In January 2017, the FASB issued ASU No. 2017-04, “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment,” which simplifies the test for goodwill impairment by eliminating Step 2 of the goodwill impairment analysis, while retaining the option to perform an initial qualitative assessment for a reporting unit to determine if a quantitative impairment test is required. ASU 2017-04 is effective in the Company’s Fiscal 2021 with early adoption permitted and should be applied on a prospective basis. The Company is currently evaluating the impact of ASU 2017-04 on its consolidated financial statements. Share-Based Compensation In May 2017, the FASB issued ASU No. 2017-09, "Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting", which simplifies modification accounting for entities that change the terms or conditions of share-based awards. ASU 2017-09 is effective for the Company’s Fiscal 2019 with early adoption permitted and is required to be applied on a prospective basis. The Company will evaluate the impact of ASU 2017-09 on any future changes to the terms and conditions of its share-based compensation awards.
Receivables, net	Receivables are presented net of allowances for sales returns, discounts, markdowns, operational chargebacks and doubtful accounts. Sales returns are determined based on an evaluation of current market conditions and historical returns experience. Discounts are based on open invoices where trade discounts have been extended to customers. Markdowns are based on wholesale customers' sales performance, seasonal negotiations with customers, historical deduction trends and an evaluation of current market conditions. Operational chargebacks are based on deductions taken by customers, net of expected recoveries. Such provisions, and related recoveries, are reflected in net sales. The Company's allowance for doubtful accounts is determined through analysis of periodic aging of receivables that are not covered by insurance and assessments of collectability based on an evaluation of historic and anticipated trends, the financial conditions of the Company’s customers and the impact of general economic conditions. The past due status of a receivable is based on its contractual terms. Amounts deemed uncollectible are written off against the allowance when it is probable the amounts will not be recovered.
