Hello.
1. a wrinkled shirt
2. a rumpled shirt
These two mean the same thing, don't they?
Dear Daruma:
They mean basically the same thing.
To my ear 'rumpled' has the connotation of being creased and disordered through wear. ('He had a rumpled look after spending a sleepless night on the train.')
'Wrinkled,' on the other hand, means creased in an untidy way.
Also, skin can be wrinkled, but not rumpled.
I hope this is helpful,
Petra
