Forbidding nurse bandaging hip (8)
I believe the answer is:
sinister
'forbidding' is the definition.
(synonyms)
'nurse bandaging hip' is the wordplay.
'nurse' becomes 'sister' (a female nurse might be called sister).
'bandaging' means one lot of letters goes inside another.
'hip' becomes 'in' (both can mean fashionable).
'sister' enclosing 'in' is 'SINISTER'.
(Other definitions for sinister that I've seen before include "Spooky" , "not right!" , "can be injurious" , "'Ominous, baleful (8)'" , "Malign, ominous" .)
