Frenchman's cap (5)
I believe the answer is:
beret
'frenchman's cap' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for beret that I've seen before include "French-style hat" , "cover for commandos" , "Soft round cap without a peak" , "Frenchman's flat hat" , "Soft flat hat" .)
