TWO workout shorts - PUMA and ASOS - NWT new with tags

Bought both of these but they are too large and the return window is closed. PUMA is listed as a size L but fits like an XL. ASOS is listed as a size US 8 but fits like a U.S. XL. Never worn, but tried on once. Both are sold in one sale. Both were $30 new. Selling for 1/2 for both together.
