Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The accompanying unaudited condensed consolidated financial statements of Chico's FAS, Inc., a Florida corporation, and its wholly-owned subsidiaries (the "Company") have been prepared in accordance with the instructions to Form 10-Q and do not include all of the information and notes required by accounting principles generally accepted in the U.S. for complete financial statements. In the opinion of management, such interim financial statements reflect all normal, recurring adjustments considered necessary to present fairly the condensed consolidated financial position, the results of operations and cash flows for the interim periods presented. All significant intercompany balances and transactions have been eliminated in consolidation. The fiscal year ended January 29, 2022 balance sheet data was derived from audited consolidated financial statements. For further information, refer to the consolidated financial statements and notes thereto for the fiscal year ended January 29, 2022, included in the Company's Annual Report on Form 10-K for the fiscal year ended January 29, 2022 filed with the Securities and Exchange Commission ("SEC") on March 15, 2022 ("2021 Annual Report on Form 10-K"). As used in this report, all references to "we," "us," "our", "the Company" and "Chico's FAS," refer to Chico's FAS, Inc. and all of its wholly-owned subsidiaries. Our fiscal years end on the Saturday closest to January 31 and are designated by the calendar year in which the fiscal year commences. Operating results for the thirteen and twenty-six weeks ended July 30, 2022 are not necessarily indicative of the results that may be expected for the entire year. COVID-19 Pandemic Update The novel strain of coronavirus (‘‘COVID-19’’) pandemic (the ‘‘COVID-19 pandemic’’ or the ‘‘pandemic’’) resulted in significant challenges across our business since March 2020 and is expected to continue to disrupt our business operations for fiscal 2022 to varying degrees. In response to the pandemic, many of our markets imposed limitations, varying by market and in frequency, on the access to the Company’s store fleet, including temporary store closures and/or a reduction in hours, staffing and capacity. We continue to focus on evolving consumer demand emerging from the pandemic and have accelerated our transformation to a digital-first company, fast-tracking numerous innovation and technology investments across all three of our brands. Even as governmental restrictions have relaxed and markets are primarily open, we expect continued uncertainty and volatility on our business operations, operating results and operating cash flows as the ongoing economic impacts and health concerns associated with the pandemic continue to affect consumer behavior, spending levels and shopping preferences and cause disruptions to the supply chain and increase our raw materials and freight costs. Due to the uncertainty over the duration and severity of the economic and operational impacts of the pandemic, the adverse impacts of the pandemic may continue throughout our fiscal year 2022. Reclassifications Certain reclassifications have been made to the prior period's financial statements to enhance the comparability with the current year's financial statements. As a result, certain line items have been amended in the unaudited condensed consolidated balance sheets to conform to the current period's presentation. Adoption of New Accounting Pronouncements There were no new accounting pronouncements adopted by the Company during the thirteen and twenty-six weeks ended July 30, 2022.
