Fabric dealer (6)
I believe the answer is:
draper
'fabric dealer' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for draper that I've seen before include "Dealer in fabrics and sewing materials" , "Dealer in cloth and clothing" , "Dealer in fabrics etc" , "One sells clothes" , "Seller of textiles" .)
