My group showing bodice (6)
I believe the answer is:
corset
'bodice' is the definition.
(I've seen this before)
'my group' is the wordplay.
'my' becomes 'cor' (I've seen this in other clues).
'group' becomes 'set' (set is a kind of group).
'cor'+'set'='CORSET'
'showing' is the link.
(Other definitions for corset that I've seen before include "Tight bodice" , "Tight-fitting undergarment" , "female garment!" , "Close-fitting foundation garment" , "Tight-fitting bodice" .)
