Elegantly stylish (4)
I believe the answer is:
chic
'elegantly stylish' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for chic that I've seen before include "Fashionably elegant" , "Elegant and sophisticated" , "Stylishness, elegance" , "Elegantly fashionable" , "Unwanted sounds" .)
