Bit of body art, for short (3)
I believe the answer is:
tat
'bit of body art for short' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for tat that I've seen before include "Junk; make lace" , "Tasteless rubbish" , "trashy clothing" , "Worthless goods" , "Tawdry stuff" .)
