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 Loan. If the borrowing base is less than the outstanding Term Loan at any measurement period, then the Company would be required to repay a portion of the Term Loan to eliminate such shortfall. The Company is also required to raise $2.0 million of additional capital before May 4, 2019; however, this will not be required if the Company’s average working capital exceeds an agreed upon level at the close of the Company’s fiscal year ending February 2, 2019. Events of default include, among other things, the occurrence of a change of control of the Company, and a default under the Term Loan agreement would also trigger a default under the Junior Notes agreements.
