Organic cotton romper set, gentle material for babies. - Colors: 2 White, 1 Gray, 1 Light Pink, 1 Salmon Pink, 1 Light Blue - Brand: H&M - Material: Organic Cotton - Size: 0-1 month Thank you for looking. Sleeve length: Short sleeve Design: Plain All are newborn size 50-60. My daughter wore them until around 3 months old, so I think they can be worn even after the newborn stage if the baby has an average build! The light blue romper at the bottom right is also H&M, but it was a different product from the other 5-piece set. However, since the sizing is the same, I'm selling them together! It's a set of 5 simple and cute rompers, and one romper with cute colors and shoulder ruffles. They are still wearable, so I would be happy if someone could use them!
