Thin Sleeveless Vest The underwear is visible, but only the body line is faintly visible, so it can be used by a variety of people. The neckline is close to a round neck, so it goes well with both blouses with collars and shirts without collars. It can be worn casually or for a stylish occasion. It's a pale lemon color that's easy to match with any color. It can be used regardless of the season depending on the innerwear. The innerwear in the photo is included.
