This is a set of Uniqlo baby clothes. My daughter, who was born in winter, wore these as underwear and pajamas for about two months. Since she rarely spit up or had diaper leaks, I don't think there are any noticeable stains. Please check the photos. I washed them and put them away in a Ziploc-like bag. I will pack and ship them in the bag they were stored in. This is a set of 4 pieces, with Miffy and floral patterns. Colorful floral cotton romper, comfortable to wear. - Design: Floral - Color: Multicolor - Material: Cotton - Size: 80cm - Style: Romper Thank you for looking.
