Line of credit facility, borrowing capacity, description					The Company is required to maintain a borrowing base comprising the value of the Company’s trademarks that exceeds the outstanding balance of the term loans. If the borrowing base is less than the outstanding term loans at any measurement period, then the Company would be required to repay a portion of the term loans to eliminate such shortfall. Events of default include, among other things, the occurrence of a change of control of the Company, and a default under the senior secured credit facility would also trigger a default under the Junior Notes agreements. The Company’s operating results for the twelve months ended November 2, 2019 and February 1, 2020 resulted in a violation of the minimum Adjusted EBITDA covenant, which is an event of default. However, the Company’s lender has agreed to forbear from enforcing its rights under the senior secured credit facility through July 27, 2020. (See Note 1, Liquidity and Going Concern.)
