This item was given to me as a used item, and I've been using it as loungewear at home. It's size 110, but it runs small, so it seems like it can be worn from size 100. As shown in the last image, there's a snap button on one shoulder, but you might not need to fasten it every time. There's a small spot of dirt on one of the cuffs, so I've marked it as having some scratches and dirt. Since I wore it regularly, there might be other overlooked imperfections. It's made of warm fleece fabric, so it seems perfect for when it starts to get chilly. My child, who loves Hello Kitty, also liked wearing it♡ This is a used item, so please understand that there may be other overlooked imperfections. Please refrain from purchasing if you are concerned about the condition.
