This is a lovely gift from the UK. The material is polyester, but it's thick and looks warm. It's a UK size 11-12, so I think it's about the same as Uniqlo Kids size 130-140cm. Please refer to the following for the size details. Measurements taken by hand: Shoulder width: 33cm Length: 50cm Width: 44cm This item has been stored at home, so please refrain from bidding if you are concerned about this.
