Cares about European pleat (6)
I believe the answer is:
crease
'pleat' is the definition.
(crease in a skirt)
'cares about european' is the wordplay.
'about' indicates anagramming the letters.
'european' becomes 'e' (abbreviation e.g. EU).
'cares' with letters rearranged gives 'creas'.
'creas'+'e'='CREASE'
(Other definitions for crease that I've seen before include "Fold; batsman's position" , "Folded line" , "iron this out" , "Fold in clothes" , "Furrow, wrinkle" .)
