Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The unaudited Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q have been prepared by Christopher & Banks Corporation and its subsidiaries (collectively referred to as “Christopher & Banks”, “the Company”, “we” or “us”) pursuant to the current rules and regulations of the United States ("U.S.") Securities and Exchange Commission ("SEC"). Accordingly, certain information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the U.S. have been omitted, pursuant to such rules and regulations. These unaudited Condensed Consolidated Financial Statements, except the Condensed Consolidated Balance Sheet as of February 2, 2019 derived from the Company's audited financial statements, should be read in conjunction with the audited financial statements and related notes included in the Company's Annual Report on Form 10-K for the fiscal year ended February 2, 2019. The results of operations for the interim periods shown in this report are not necessarily indicative of results to be expected for the full fiscal year. In the opinion of management, the information contained herein reflects all adjustments, consisting only of normal adjustments, except as otherwise stated in these notes, considered necessary to present fairly our financial position, results of operations, and cash flows as of November 2, 2019, November 3, 2018 and for all periods presented. Recently issued accounting pronouncements In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement - Disclosure Framework (Topic 820). The updated guidance improves the disclosure requirements for fair value measurements. The updated guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. We are currently evaluating the impact of adopting the updated provisions. Recently adopted accounting pronouncements In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The Company adopted the new standard, ASC 842, Leases, and all related amendments on February 3, 2019 using the "Comparatives Under 840 Option" for all leases in which we applied the previous standard, ASC 840, Leases, and recognized the effects of applying ASC 842 as a cumulative-effect adjustment to retained earnings as of February 3, 2019. We elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed us to carryforward the historical lease classification. In addition, we elected certain practical expedients and accounting policies including the lessee practical expedient to not separate lease components. We made an accounting policy election to keep leases with an initial term of 12 months or less off of the balance sheet. We recognize those lease payments in the Condensed Consolidated Statements of Operations on a straight-line basis over the lease term. Adoption of the standard resulted in the recognition of operating lease assets and operating lease liabilities of $134.9 million and $153.9 million, respectively, as of February 3, 2019. The operating lease asset recorded at adoption of the standard represents the capitalization of operating lease assets and the reclassification of prepaid rent and leasehold acquisition costs, offset by the reclassification of straight-line rent accruals, tenant improvement allowances and vacant space reserves. At adoption, we recorded an adjustment to retained earnings of $3.3 million, which includes the recognition of the deferred gain on the sale-leaseback transaction of our corporate headquarters facility. Additional information and disclosures required by the new standard are contained in Note 9 - Leases. In August 2018, the SEC adopted a final rule under SEC Release No. 33-10532, Disclosure Update and Simplification that amends certain disclosure requirements that were redundant, duplicative, overlapping, outdated or superseded. The amendments also expanded the disclosure requirements on the analysis of shareholders' equity for interim financial statements, in which registrants must now analyze changes in shareholders’ equity, in the form of reconciliation, for the current and comparative year-to-date periods, with subtotals for each interim period. This final rule was effective on November 5, 2018. As of the first quarter of Fiscal 2019, the Company has adopted all relevant disclosure requirements, including the shareholders’ equity interim disclosures. We reviewed all other significant newly-issued accounting pronouncements and concluded they are either not applicable to our operations or that no material effect is expected on our consolidated financial statements as a result of future adoption.
