Clothing I adjusted for restaurant (9)
I believe the answer is:
brasserie
'restaurant' is the definition.
(brasserie is a kind of restaurant)
'clothing i adjusted' is the wordplay.
I cannot quite understand how this works, but
'clothing' could be 'bra' (bra is a kind of clothing) and 'bra' is found within the answer.
'i' is found in the answer.
This may be the basis of clue (or it may be nonsense).
'for' is the link.
(Other definitions for brasserie that I've seen before include "French-style restaurant" , "eating place" , "Simple restaurant" , "Where to eat" , "Small restaurant serving alcohol as well as food" .)
