Supports cash cut (4)
I believe the answer is:
bras
'supports' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for bras that I've seen before include "Garments with cups" , "supports" , "They support" , "Female undergarments" , "Items in womenswear" .)
