Fold model garment (7)
I believe the answer is:
doublet
This clue might be a double definition.
'fold model' is the first definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'garment' is the second definition.
(doublet is a kind of garment)
Can you help me to learn more?
(Other definitions for doublet that I've seen before include "would be seen in battle" , "Formerly, a man's close-fitting jacket" , "Pair of similar things" , "Close-fitting jacket (14th to 17th century)" , "Short jacket" .)
