Never-worn garment in a state? (3,6)
I believe the answer is:
new jersey
'a state?' is the definition.
(New Jersey is an example)
'never-worn garment' is the wordplay.
'never-worn' becomes 'new'.
'garment' becomes 'jersey' (jersey is a kind of garment).
'new'+'jersey'='NEW JERSEY'
'in' acts as a link.
(Other definitions for new jersey that I've seen before include "Coastal US state" , "Newark's state" , "US state; seasonal gift?" , "The Garden State" , "Recently-purchased clothing" .)
