Dancer's garment (7)
I believe the answer is:
leotard
'dancer's garment' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for leotard that I've seen before include "Gymnast's tight costume" , "Acrobat's costume" , "Skin-tight garment worn by acrobats" , "Acrobat costume" , "Garment used eg in ballet or yoga" .)
