Individually women will come in to support bikinis etc (9)
I believe the answer is:
beachwear
'bikinis etc' is the definition.
'individually women will come in to support' is the wordplay.
'individually' becomes 'each' (I've seen this before).
'women' becomes 'w'.
'will come in to' is an insertion indicator.
'support' becomes 'bear' (I've seen this before).
'each'+'w'='eachw'
'eachw' put inside 'bear' is 'BEACHWEAR'.
(Other definitions for beachwear that I've seen before include "Holiday clothing" , "Trunks, bikinis etc" , "skimpy garments" , "Bikini, for instance" , "Speedos for one" .)
