Notice clothes to deal with (7)
I believe the answer is:
address
'deal with' is the definition.
(synonyms)
'notice clothes' is the wordplay.
'notice' becomes 'ad' (short for advert).
'clothes' becomes 'dress' (dress is a kind of clothes).
'ad'+'dress'='ADDRESS'
'to' acts as a link.
(Other definitions for address that I've seen before include "Form of identification for building" , "Give a talk to" , "Where one lives" , "lecture?" , "Call" .)
