Nature of Operations and Basis of Presentation [Abstract]
Nature of Operations	A. Nature of Operations Duluth Holdings Inc. (“Duluth Trading” or the “Company”), a Wisconsin corporation, is a lifestyle brand of men’s and women’s casual wear, workwear and accessories sold exclusively through the Company’s own direct and retail channels. The direct segment, consisting of the Company’s website and catalogs, offers products nationwide. In 2010, the Company added retail to its omni-channel platform with the opening of its first store. Since then, Duluth Trading has expanded its retail presence, and as of October 30, 2016, the Company operated 12 retail stores and two outlet stores across the Midwestern and Eastern United States. The Company’s products are marketed under the Duluth Trading brand, with the majority of products being exclusively developed and sold as Duluth Trading branded merchandise. The Company has two classes of authorized common stock: Class A common stock and Class B common stock. The rights of holders of Class A common stock and Class B common stock are identical, except for voting and conversion rights. Each share of Class A common stock is entitled to ten votes per share and is convertible at any time into one share of Class B common stock. Each share of Class B common stock is entitled to one vote per share. The Company’s Class B common stock trades on the NASDAQ Global Select Market under the symbol “DLTH.” On November 25, 2015, the Company converted from an “S” corporation to a “C” corporation for federal income tax purposes under Section 1362 of the Internal Revenue Code of 1986, as amended (the “Code”), and the Company completed its initial public offering (“IPO”). Refer to the Company’s consolidated financial statements and notes included in the Company’s annual report on Form 10-K for the fiscal year ended January 31, 2016, for additional information related to the Company’s IPO. During the first quarter of fiscal 2016, the Company paid the remaining $0.2 million balance of its final “S” corporation distribution, which resulted in a total final distribution of $46.6 million from the termination of the Company’s “S” corporation status.
Basis of Presentation	B. Basis of Presentation The condensed consolidated financial statements are prepared in accordance with U.S. Generally Accepted Accounting Principles (“U.S. GAAP”). The accompanying condensed consolidated financial statements include the accounts of the parent, Duluth Holdings Inc., and its wholly-owned subsidiary, Duluth Trading Company, LLC. Effective October 3, 2016, Duluth Trading Company, LLC was dissolved and no longer consolidated, which did not impact the Company’s consolidated financial statements. The Company also consolidates Schlecht Retail Ventures LLC (“SRV”) as a variable interest entity (see Note 4 “Variable Interest Entity”). All intercompany balances and transactions have been eliminated. The Company’s fiscal year ends on the Sunday nearest to January 31 of the following year. Fiscal 2016 is a 52-week period and ends on January 29, 2017. Fiscal 2015 was a 52-week period and ended on January 31, 2016. The three and nine months of fiscal 2016 and fiscal 2015 represent the Company’s 13 and 39-week periods ended October 30, 2016 and November 1, 2015, respectively. The accompanying condensed consolidated financial statements as of and for the three and nine months ended October 30, 2016 and November 1, 2015 have been prepared by the Company, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and, in the opinion of the Company, include all adjustments (which are normal and recurring in nature) necessary to present fairly the financial position, results of operations and cash flows of the Company for the interim periods presented. Certain information and note disclosures normally included in consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such SEC rules and regulations as of and for the three and nine months ended October 30, 2016 and November 1, 2015. These interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company’s annual report on Form 10-K for the fiscal year ended January 31, 2016.
Seasonality of Business	C. Seasonality of Business The Company’s business is affected by the pattern of seasonality common to most retail apparel businesses. Historically, the Company has recognized a significant portion of its revenue and operating profit in the fourth fiscal quarter of each year as a result of increased sales during the holiday season.
Pro Forma Net Income Information	D. Pro Forma Net Income Information For the three and nine months ended November 1, 2015, the pro forma net income information gives effect to the conversion of the Company to a “C” corporation on November 25, 2015. Prior to such conversion, the Company was an “S” corporation and generally not subject to income taxes. The pro forma net income, therefore, includes an adjustment for income tax expense on the income attributable to controlling interest as if the Company had been a “C” corporation as of February 4, 2013 at an assumed combined federal, state and local effective tax rate of 40%, which approximates the calculated statutory rate for each period. No pro forma income tax expense was calculated on the income attributable to noncontrolling interest because this entity did not convert to a “C” corporation. For the three and nine months ended November 1, 2015, the pro forma basic and diluted net income per share of Class A and Class B common stock is computed using the pro forma net income, as discussed above.
Restricted Cash	E. Restricted Cash The Company’s restricted cash is held in an escrow account and is used to pay a portion of the construction loans entered into by third party landlords (the “Landlords”) in connection with the Company’s retail store leases. The restricted cash is disbursed based on the escrow agreement entered into by and among the Landlords, the Company and the escrow agent.
Build-to-Suit Lease	F. Build-to-Suit Lease The Company may at times be involved in the construction of stores to be leased by the Company and, depending on the extent to which the Company is involved, the Company may be deemed the owner of the leased premises for accounting purposes during the store construction period. For leases that the Company is deemed the owner of the property during the construction period, upon commencement of the construction project, the Company is required to capitalize the cash and non-cash assets contributed by the landlord for construction as property and equipment on the Company’s Condensed Consolidated Balance Sheets. Upon the completion of the construction project, the Company performs an analysis on the lease to determine if the Company qualifies for sale-leaseback treatment. For those qualifying leases, the deemed landlord financing liability and the associated property and equipment are removed and the difference is reclassified to either prepaid or deferred rent and amortized over the lease term as an increase or decrease to rent expense. If the lease does not qualify for sale-leaseback treatment, the deemed landlord financing liability is amortized over the lease term based on the rent payments in the lease agreement. As of October 30, 2016, the Company capitalized $2.0 million in property and equipment and recorded a corresponding non-current liability related to build-to-suit lease transactions in which the Company is considered the owner for accounting purposes.

Disclosure of accounting policy for leasing arrangements (both lessor and lessee). This disclosure may address (1) lease classification (that is, operating versus capital), (2) how the term of a lease is determined (for example, the circumstances in which a renewal option is considered part of the lease term), (3) how rental revenue or expense is recognized for a lease that contains rent escalations, (4) an entity's accounting treatment for deferred rent, including that which arises from lease incentives, rent abatements, rent holidays, or tenant allowances (5) an entity's accounting treatment for contingent rental payments and (6) an entity's policy for reviewing, at least annually, the residual values of sales-type and direct-finance leases. The disclosure also may indicate how the entity accounts for its capital leases, leveraged leases or sale-leaseback transactions.
