Female dressing in Welsh town (5)
I believe the answer is:
flint
'welsh town' is the definition.
(I've seen this before)
'female dressing' is the wordplay.
'female' becomes 'f' (common abbreviation).
'dressing' becomes 'lint' (material used for dressing wounds).
'f'+'lint'='FLINT'
'in' is the link.
(Other definitions for flint that I've seen before include "Welsh county" , "Hard kind of stone -- Welsh town on the Dee estuary" , "Hard grey rock" , "Hard stone that sparks if struck against steel" , "castle in Wales" .)
