Body image, briefly (3)
I believe the answer is:
tat
'body image briefly' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for tat that I've seen before include "Tawdry and shabby article" , "Shoddy stuff (colloq.)" , "Worthless items" , "Shoddy article" , "What you get for tit" .)
