Misgiving about the foreign garment (7)
I believe the answer is:
doublet
'garment' is the definition.
(doublet is a kind of garment)
'misgiving about the foreign' is the wordplay.
'misgiving' becomes 'doubt' (I've seen this before).
'about' means one lot of letters goes inside another.
'the foreign' becomes 'le' ('the' in French).
'doubt' enclosing 'le' is 'DOUBLET'.
(Other definitions for doublet that I've seen before include "Padded jacket; pair" , "Close-fitting padded jacket of Tudor and Stuart England" , "Pairing" , "Formerly, a man's close-fitting jacket" , "Close-fitting jacket (14th to 17th century)" .)
