Suit option (4)

Ross

I believe the answer is:

vest

'suit option' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for vest that I've seen before include "Upper undergarment, singlet" , "Waistcoat (in USA)" , "An American man's waistcoat" , "Top" , "Undergarment for vets" .)

I've seen this clue in The Wall Street Journal.
