If I wear an item and I need to return it for whatever reason, I always wash it. I would never send back worn dirty clothing.
i have never returned anything because it wrinkles. I wear mostly 100% cotton and it always wrinkles as does linen and other natural fabrics....it is supposed to.
if you do not want to iron, buy polyester and other non wrinkling fabrics.
QVC does take back items in any condition within 30 days of purchase.
