The long-sleeved T-shirts are from next. I bought them in a set of 5. The leggings are a mix, from UNIQLO, Nishimatsuya, and next. The long-sleeved T-shirts are size 104cm. The gray leggings are 110cm, and the rest are 100cm. There may be slight size differences depending on the item, so would these be suitable for children aged 90cm to 100cm? These items were all worn at nursery, so please understand that they are used. I will remove the name stickers and cut off any parts with stamps before shipping. If you have any questions, please ask before purchasing.
