Skin art (6)
I believe the answer is:
tattoo
'skin art' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for tattoo that I've seen before include "Needlework! - performed by soldiers!" , "Pointedly design" , "Picture dyed into the skin" , "Design on skin - military show" , "hide design?" .)
