Body shape (8)
I believe the answer is:
physique
'body shape' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for physique that I've seen before include "Constitution of the human body" , "Person's build and muscular development" , "Form" , "Bodily type, build, or constitution" , "Shape and size of a person's body" .)
