Request time to make feature of dress (5)
I believe the answer is:
pleat
'feature of dress' is the definition.
(as in a pleated skirt)
'request time' is the wordplay.
'request' becomes 'plea' (plea is a kind of request).
'time' becomes 't' (abbreviation).
'plea'+'t'='PLEAT'
'to make' is the link.
(Other definitions for pleat that I've seen before include "Gathering" , "Leapt (anag)" , "Crease" , "Fold pressed or stitched into cloth" , "Fold formed in fabric" .)
