Organization, Consolidation and Presentation of Financial Statements [Abstract]
Fiscal Period, Policy	We operate on a retail accounting calendar. Our fiscal year ends on the last Monday in January and typically has 13 four-week accounting periods. For clarity of presentation, we generally label all fiscal year ends as if the fiscal year ended January 31. Accordingly, the fiscal year ended January 30, 2012 is referred to herein as the fiscal year ended January 31, 2012 or fiscal 2012, and the fiscal year ending January 28, 2013 is referred to herein as the fiscal year ending January 31, 2013 or fiscal 2013. The first quarter of our fiscal year has four periods, or 16 weeks. All other quarters generally have three periods, or 12 weeks.

Disclosure of accounting policy for determining an entity's fiscal year or other fiscal period. This disclosure may include identification of the fiscal period end-date, the length of the fiscal period, any reporting period lag between the entity and its subsidiaries, or equity investees. If a reporting lag exists, the closing date of the entity having a different period end is generally noted, along with an explanation of the necessity for using different closing dates. Any intervening events that materially affect the entity's financial position or results of operations are generally also disclosed.
