Accounting Policies [Abstract]
SIGNIFICANT ACCOUNTING POLICIES	SIGNIFICANT ACCOUNTING POLICIES Cash and Cash Equivalents - Cash and cash equivalents include bank deposit accounts, money market accounts and other highly liquid investments with original maturities of 90 days or less. At October 27, 2012, substantially all of the cash and cash equivalents were invested in U.S. Treasury bills with original maturities of 90 days or less and overnight federally-sponsored agency notes. Short-term Investments - Short-term investments consist of investments in securities with remaining maturities of less than one year, excluding investments with original maturities of 90 days or less. At October 27, 2012, short-term investments consisted solely of U.S. Treasury bills with remaining maturities ranging from less than one month to six months. These investments are classified as held-to-maturity and their market values approximate their carrying values. Inventories - We record inventory at the lower of cost or market (“LCM”). Cost is determined using the first-in, first-out method. We capitalize into inventory certain warehousing and freight delivery costs associated with shipping our merchandise to the point of sale. We periodically review quantities of inventories on hand and compare these amounts to the expected sales of each product. We record a charge to cost of goods sold for the amount required to reduce the carrying value of inventory to estimated net realizable value. Landlord Contributions - We typically receive reimbursement from landlords for a portion of the cost of leasehold improvements for new stores and, occasionally, for renovations and relocations. These landlord contributions are initially accounted for as an increase to deferred rent and as an increase to prepaid expenses and other current assets when the related store is opened. When collected, we record cash and reduce the prepaid expenses and other current assets account. The collection of landlord contributions is presented in the Condensed Consolidated Statements of Cash Flows as an operating activity. The deferred rent is amortized over the lease term in a manner that is consistent with our policy to straight-line rent expense over the term of the lease. The amortization is recorded as a reduction to sales and marketing expense, which is consistent with the classification of lease expense. Gift Cards and Certificates - We sell gift cards and gift certificates to individuals and companies. Our incentive gift certificates are used by various companies as a reward for achievement for their employees. We also redeem proprietary gift cards and gift certificates marketed by third-party premium/incentive companies. We record a liability when a gift card/certificate is purchased. As the gift card/certificate is redeemed, we reduce the liability and record revenue. Substantially all of our gift cards/certificates do not have expiration dates and they are all subject to state escheatment laws. Based on historical experience, gift cards/certificates redemptions after the escheatment due date are remote and we recognize any income (also referred to as “breakage”) on these unredeemed gift cards/certificates on a specific identification basis on the escheatment due date. Tuxedo Rental Products - Revenues from tuxedo rental products are recognized on a gross basis upon delivery of rental products to customers. When a customer orders a tuxedo rental from us, an order is placed with a national distributor who delivers the product to our stores, typically within several days of intended use. The national distributor owns the rental product and charges the Company a rental cost for each rental and delivery which is recorded to "Costs of goods sold". Equity Compensation -We account for our equity awards in accordance with FASB ASC 718, “Share-Based Payment” (“ASC 718”), which requires the compensation cost resulting from all share-based awards to be recognized in the financial statements. The amount of compensation is measured based on the grant-date fair value of the awards and is recognized over the vesting period of the awards. The vesting of awards to both the officers and directors is subject to service conditions being met, currently ranging from one to three years. Additionally, the vesting of awards to officers is subject to performance conditions being met in the fiscal year that the awards are granted such as, among other things, the attainment of certain annual earnings and performance goals. For these officer awards, we estimate the probability that such goals will be attained based on results-to-date at each interim quarter-end and record compensation cost to "General and administrative expense" for these awards based on the awards projected to vest. Share-based compensation expense recognized for the third quarter and first nine months of fiscal year 2012 related to equity awards issued under the Jos. A. Bank Clothiers, Inc. 2010 Equity Incentive Plan (“Equity Incentive Plan”) was $0.2 million and $1.6 million, respectively, and the tax benefit recognized related to this compensation was $0.1 million and $0.6 million, respectively. Share-based compensation expense recognized for the third quarter and first nine months of fiscal year 2011 was $0.7 million and $2.0 million, respectively, and the tax benefit recognized related to this compensation was $0.3 million and $0.8 million, respectively. Recently Issued Accounting Standards - In May 2011, the FASB issued ASU 2011-04, “Fair Value Measurement” (“ASU 2011-04”). ASU 2011-04 is intended to create consistency between GAAP and International Financial Reporting Standards (“IFRS”) on the definition of fair value, the guidance on how to measure fair value, and on what to disclose about fair value measurements. ASU 2011-04 was effective for financial statements issued for fiscal periods beginning after December 15, 2011, with early adoption prohibited for public entities. The adoption of ASU 2011-04 for fiscal year 2012 did not have a material impact on our consolidated financial statements. Recently Proposed Amendments to Accounting Standards - In August 2010, the FASB issued an exposure draft, “Leases” (the “Exposure Draft”), which would replace the existing guidance in ASC 840, “Leases.” Under the Exposure Draft, a lessee's rights and obligations under all leases, including existing and new arrangements, would be recognized as assets and liabilities, respectively, on the balance sheet. In July 2011, the FASB made the decision to issue a revised exposure draft; however, deliberations are still ongoing and the FASB currently plans to issue a revised exposure draft for comment during 2013. The timing of the issuance of a final standard is uncertain at this time. If this lease guidance becomes effective on the terms currently proposed by FASB, it will likely have a significant impact on our consolidated financial statements. However, as the standard-setting process is still ongoing, we are unable to determine at this time the impact this proposed change in accounting may have on our consolidated financial statements.
