Good skill, guys admitted, producing an item of clothing (7)
I believe the answer is:
garment
'an item of clothing' is the definition.
(I've seen this before)
'good skill guys admitted' is the wordplay.
'good' becomes 'g' (abbreviation).
'skill' becomes 'art' (I've seen this before).
'guys' becomes 'men'.
'admitted' means one lot of letters goes inside another.
'art' enclosing 'men' is 'arment'.
'g'+'arment'='GARMENT'
'producing' is the link.
(Other definitions for garment that I've seen before include "coat, say" , "Covering" , "Grant me (anag.)" , "Raiment" , "An article of clothing (7)" .)
