I believe the answer is:

doublet

I'm a little stuck... Click here to teach me more about this clue!

'wear' is the definition.
(doublet is a kind of wear)

I can't explain the remainder of the clue.

(Other definitions for doublet that I've seen before include "Pairing" , "would be seen in battle" , "Padded jacket; pair" , "Short jacket" , "Close-fitting jacket (14th to 17th century)" .)

I've seen this clue in the Evening Standard.
