Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for annual audited financial statements. In our opinion, all adjustments (consisting primarily of normal and recurring adjustments) considered necessary for a fair presentation have been included. Due to the seasonality of our business, results for any quarter are not necessarily indicative of the results that may be achieved for a full fiscal year. These Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended February 1, 2020, filed with the Securities and Exchange Commission (“SEC”) on June 15, 2020. As used herein, the terms “we,” “our,” “us” and “Stein Mart” refer to Stein Mart, Inc. and its wholly-owned subsidiaries. The Company is filing this Quarterly Report on Form 10-Q beyond the deadline for which the Company was originally required to file it in reliance on the filing extension provided by the SEC’s Order under Section 36 of the Securities Exchange Act of 1934, as amended, dated March 4, 2020 (Release No. 34-88318), as modified on March 25, 2020 (Release No. 34-88465) (the “Order”). On April 23, 2020, the Company filed a Current Report on Form 8-K (the “Form 8-K”) to indicate its intention to rely on the Order and delay the filing of its Quarterly Report for the first quarter ended May 2, 2020, which was originally due to be filed with the SEC on or before June 16, 2020. Consistent with the Company’s statements in the Form 8-K, the Company was unable to file the Quarterly Report until July 16, 2020 due to circumstances related to the coronavirus (“COVID-19”) pandemic. In particular, the Company required additional time due to its previously announced reduction in staff, suspension of in-person operations at its corporate headquarters, and temporary closure of its stores for an unknown period of time, as well as other financial and operational concerns associated with or caused by the COVID-19 pandemic. These conditions caused significant disruptions to the Company’s operations requiring key personnel to devote considerable time and resources to respond to the emerging impacts to its business, which limited their availability to complete the Quarterly Report and to thoroughly evaluate the impact of the COVID-19 pandemic.
Going Concern	Going Concern During March 2020, a global pandemic was declared by the World Health Organization related to the rapidly growing outbreak of COVID-19. The pandemic has significantly impacted the economic conditions in the U.S., accelerating during the first half of March, as federal, state and local governments reacted to the public health crisis, creating significant uncertainties in the U.S. economy. In March 2020, we announced the temporary closure of all stores for an unknown period of time and significant actions taken to mitigate the ongoing impact of the COVID-19 pandemic on our cash flows to protect our business and associates for the long term in response to the crisis. Such actions include targeted reductions in discretionary operating expenses such as advertising and payroll expenses, including furloughing a significant number of our employees and temporarily reducing the payroll of remaining employees, reducing capital expenditures, reducing merchandise receipts, and utilizing funds available under our Revolving Credit Facility and Promissory Note. Further, we have sought and are seeking extended payment terms with all vendors, including merchandise, expense and rent vendors. We started reopening stores on April 23, 2020 as government jurisdictions have allowed, and as of June 15, 2020, we have reopened all of our stores with limited operating hours. We are unable to predict if additional periods of store closures will be needed or mandated. Continued impacts of the pandemic have had a material adverse impact on our revenues, earnings, liquidity and cash flows, and may require significant additional actions in response, including, but not limited to, further employee furloughs, reduced store hours, store closings, expense reductions or discounting of pricing of our products, all in an effort to mitigate such impacts. The extent of the impact of the pandemic on our business and financial results will depend largely on future developments, including the duration of the spread of the outbreak within the U.S., the impact on capital and financial markets and the related impact on consumer confidence and spending, all of which are highly uncertain and cannot be predicted. This situation is rapidly changing and additional impacts to the business may arise that we are not aware of currently. While the disruption is currently expected to be temporary, there is uncertainty around the duration. The ultimate impact of the pandemic on the Company’s results of operations, financial position, liquidity or capital resources cannot be reasonably estimated at this time. The significant risks and uncertainties related to the Company's liquidity described above raise substantial doubt about the Company's ability to continue as a going concern over the next twelve months. The Consolidated Financial Statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities and other commitments in the normal course of business. The accompanying Consolidated Financial Statements do not include any adjustments to reflect the possible future effects of this uncertainty on the recoverability or classification of recorded asset amounts or the amounts or classification of liabilities.
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards In August 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40). This update provides additional guidance to ASU No. 2015-5, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40), which was issued in April 2015. The amendments in this ASU align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). This ASU is effective for annual reporting periods beginning on or after December 15, 2019, and interim periods within those annual periods with early adoption permitted in any interim period for which financial statements have not yet been issued. We adopted this ASU as of February 2, 2020. The adoption of this ASU did not have a material effect on our financial condition, results of operations or cash flows.
