To Georgia, it’s a loose outer garment (4)
I believe the answer is:
toga
'a loose outer garment' is the definition.
(I've seen this in another clue)
'to georgia' is the wordplay.
'georgia' becomes 'GA' (abbreviation for the US state).
'to'+'ga'='TOGA'
'it's' acts as a link.
(Other definitions for toga that I've seen before include "Roman clothing" , "Roman citizen's robe" , "Roman gents' cloak" , "garment of old" , "Roman dress" .)
