The term 'SUIT OPTION' can be solved by the four-letter word 'VEST'. A VEST is a sleeveless garment that is worn over a shirt or blouse and under a suit jacket. It is usually made of the same material as the suit and is designed to match the suit's color and pattern. Vests are often worn for formal occasions, such as weddings, funerals, and other special events. They can also be worn casually with jeans or khakis.
