Pouch worn with kilt (7)
I believe the answer is:
sporran
'pouch worn with kilt' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for sporran that I've seen before include "Scots dress item" , "Purse worn with kilt" , "Part of Scottish outfit" , "Pouch on Highlander's belt" , "Pouch accompanying kilt" .)
