It is not taxable. You can use the cost of the clothes as a deduction and you will have no net income to pay taxes on. If the IRS questions it, then show them your documentation. Print out or screenshot from Paypal something showing that what you sold was used personal items.
Do it this way, it will zero out and not be taxed: Enter it under Wages & Income, Your 2017 Income Summary, scroll down click on Start next to Miscellaneous Income, then choose Other reportable income, answer Yes to "Any Other Taxable Income?" Under Description put "Sales of Personal Property 1099-K" and enter the amount from the 1099-K in the next box, click continue, click on "add another income item", Under Description put "Cost of Personal Property 1099-K" and enter the same amount as a negative. On the Other Miscellaneous Income Summary make sure you see the 2 items, one positive and one negative and Total is $0.
