Fortune invested in clothing (3)
I believe the answer is:
lot
'fortune' is the definition.
(as in a person's lot in life)
'invested in clothing' is the wordplay.
'invested in' indicates the answer is hidden within the clue.
'LOT' is hidden within 'clothing'.
(Other definitions for lot that I've seen before include "is to be knocked down" , "In the Bible, his wife was turned into a pillar of salt" , "Share - tons" , "Destiny - biblical character - Polish national airline" , "Could there be many at the auction?" .)
