Puts his cash into underwear (7)

Ross

I believe the answer is:

invests

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

'puts his cash' is the definition.
'invests' can be an answer for 'puts' ('invest' can be a synonym of 'put'). I am unsure of the 'his cash' bit.

'into underwear' is the wordplay.
'into' becomes 'in'.
'underwear' becomes 'vests' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'in'+'vests'='INVESTS'

Can you help me to learn more?

(Other definitions for invests that I've seen before include "Lays out, hoping for profit" , "Speculates" , "Gives significance to" , "Puts money into a venture in expectation of a return" , "Puts money into business" .)
