Apart from bras, underwear being sampled (7)
I believe the answer is:
asunder
'apart from' is the definition.
(thesaurus)
'bras underwear being sampled' is the wordplay.
'being sampled' indicates the answer is hidden within the clue (I've seen this in other clues).
'ASUNDER' can be found hidden inside 'bras underwear'.
(Other definitions for asunder that I've seen before include "(Broken) apart" , "(Break) apart" , "Into parts or pieces" , "(Split) into pieces" , "being in two" .)
