Some bikinis and shorts in beach area (5)
I believe the answer is:
sands
'beach area' is the definition.
'some bikinis and shorts' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'SANDS' is hidden within 'bikinis and shorts'.
'in' is the link.
(Other definitions for sands that I've seen before include "The Goodwin - -" , "Rubs smooth" , "Beach" , "You may see them by sea" , "Polishes (eg, wood)" .)
