Coat and bras exchanged for jumpers? (8)
I believe the answer is:
acrobats
'jumpers?' is the definition.
(people who jump)
'coat and bras exchanged' is the wordplay.
'and' is a charade indicator (letters next to each other).
'exchanged' indicates an anagram.
'coat'+'bras'='coatbras'
'coatbras' anagrammed gives 'ACROBATS'.
'for' is the link.
(Other definitions for acrobats that I've seen before include "Top performers" , "They perform feats of balance" , "Gymnastic entertainers" , "Gymnasts; tumblers" , "versatile performers" .)
