Thank you for viewing! This is a warm one-piece dress with fluffy boa material on the inside as well. It's in beautiful condition as it's hardly been worn. Size: 100 "LOOK by BEAMS mini" is a joint brand between "BEAMS mini" and Amazon, offering kids' wear that values children choosing and enjoying what they like, rather than imposing adult styles. Following the BEAMS mini concept of "fun to wear, fun to look at children's clothing" with a touch of fashion added to basic items, it supports the daily lives of energetic children with stress-free designs that are easy to change into and a wide range of sizes from baby to kids to choose from as they grow.
