Busts attractive in photo (8)
I believe the answer is:
snapshot
'photo' is the definition.
(I've seen this before)
'busts attractive' is the wordplay.
'busts' becomes 'snaps' ('snap' can be a synonym of 'bust').
'attractive' becomes 'hot'.
'snaps'+'hot'='SNAPSHOT'
'in' acts as a link.
(Other definitions for snapshot that I've seen before include "Bit of camerawork" , "Picture" , "pic" , "Pan hosts over casual photo" , "print" .)
