1. a wrinkled shirt
2. a rumpled shirt
These two mean the same thing, don't they?
I ususally say "wrinkled". I don't know if I've ever said "rumpled". They mean the same thing. Saying "my shirt is rumpled" sounds kind of funny to me for some reason. I don't know why. It is correct, though. There's no problem with saying "my shirt is rumpled".
