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 November 1, 2015, the Company operated six retail stores and two outlet stores across Minnesota, Iowa and Wisconsin. The Company’s products are marketed under the Duluth Trading Company brand, with the majority 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, as amended (the “Code”), and the Company completed its initial public offering (“IPO”). See Note 12 “Subsequent Events,” for more information.
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”). 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 2015 is a 52-week period and ends on January 31, 2016. Fiscal 2014 was a 52-week period and ended on February 1, 2015. The three and nine months of fiscal 2015 and fiscal 2014 represent the Company’s 13 and 39-week periods ended November 1, 2015 and November 2, 2014, respectively. The accompanying condensed consolidated financial statements as of and for the three and nine months ended November 1, 2015 and November 2, 2014 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 November 1, 2015 and November 2, 2014. These interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company’s Registration Statement on Form S-1, as amended (Registration No. 333-207300) (“Form S-1”), which was declared effective by the SEC on November 19, 2015.
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.
Unaudited Pro Forma Net Income Information	D. Unaudited Pro Forma Net Income Information The unaudited 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. The unaudited pro forma basic and diluted net income per share of Class A and Class B common stock is computed using the unaudited pro forma net income, as discussed above.
