Invested with underwear (4)

I believe the answer is:

vest

'underwear' is the definition.

'invested with' is the wordplay.
'with' indicates a hidden word.
'VEST' is hidden within 'invested'.

(Other definitions for vest that I've seen before include "American version of waistcoat" , "Upper undergarment, singlet" , "Sleeveless garment" , "An American man's waistcoat" , "Undergarment for vets" .)

I've seen this clue in The Mirror.
