I usually have great luck with clothes from Old Navy. However, they don't carry plus sizes in the store, only online. It's annoying but not a super inconvience. I got a sweater for Christmas that doesn't fit right, I'm too short for it. Now to send it back I have print out the return label, find a box, pack the sweater back into the box, and drive to the UPS store.
The movie theater I'm going to later has an Old Navy a two minute walk thru the mall away. But I can't return to the store. Because god forbid you wear a size 20 and want to shop where people shop. That simply cannot be.
