Fashion scheme - I admitted making garment (7)
I believe the answer is:
chemise
'garment' is the definition.
(chemise is a kind of garment)
'fashion scheme i admitted' is the wordplay.
'fashion' indicates anagramming the letters.
'admitted' is an insertion indicator (inserted letters get admitted).
'scheme' with letters rearranged gives 'chemse'.
'chemse' placed around 'i' is 'CHEMISE'.
'making' is the link.
(Other definitions for chemise that I've seen before include "Loose-fitting dress or undergarment" , "Loose-fitting shirtlike dress" , "Apron" , "Loose-fitting dress without a waist" , "garment" .)
