Skin design (6)
I believe the answer is:
tattoo
'skin design' 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 "Military call and design on the skin" , "Military display - picture on the skin" , "image on one's skin" , "Indelible mark on skin or military entertainment" , "Military parade - anchor on the biceps?" .)
