Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business Description and Basis of Presentation [Text Block]	NOTE 1 — 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. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the U.S. have been condensed, or omitted, pursuant to such rules and regulations. These unaudited condensed consolidated 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, 2013. 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, necessary to present fairly our financial position as of August 3, 2013 and February 2, 2013, our results of operations for the thirteen and twenty-six week periods ended August 3, 2013 and July 28, 2012 and our cash flows for the twenty-six week periods ended August 3, 2013 and July 28, 2012. Recently issued accounting pronouncements In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update ("ASU") No. 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. This update requires that companies present either in a single note or parenthetically on the face of the financial statements, the effect of significant amounts reclassified from each component of accumulated other comprehensive income based on its source and the income statement line items affected by the reclassification. If a component is not required to be reclassified to net income in its entirety, companies would instead cross reference to the related footnote for additional information. The guidance is effective for the Company’s interim and annual reporting periods beginning after December 15, 2012, and applied prospectively. The adoption of this guidance did not have a material impact on the Company's financial condition, results of operations or disclosures. In July 2013, the FASB issued ASU No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. This update requires that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. The guidance will be effective for the Company's interim and annual reporting periods beginning after December 15, 2013, with early adoption permitted. The update should be applied prospectively to all unrecognized tax benefits that exist at the effective date, although retrospective application is permitted. The Company does not expect adoption of this guidance to have a material impact on its financial condition, results of operations or disclosures.
