This is a layered look featuring a ribbed knit striped top with an attached vest. It's a single piece! I wore it for outings because it's cute. I only wore it for one season, so I don't see any noticeable stains. There might be some minor overlooked stains, so please refrain from purchasing if you are sensitive to such things. I'm also selling many other baby clothes. I offer discounts for multiple purchases. Brands: H&M, ZARA Baby, Gap, Petit Main, Breeze, Muji, UNIQLO, Shimamura, Birthday
