This is a set of two jumper skirts. Both have adjustable straps, and my child wore them from size 90. I think children who wear size 100 can also wear them. The shoulder straps are crisscrossed in the back, so they don't slip off, and they were easy to put on. [Embroidered Flare Skirt] Brand: Next Size: 2-3 years, 98 The embroidery is very cute. The waist is elasticated only in the back. There are traces of the shoulder strap buttons having been moved. [Denim Jumper Skirt] Brand: Gap Size: 3 years There is dirt from playing in the mud on the inside of the skirt. Please check the photos. I'm thinking of selling them as a set for now. I don't see any noticeable stains, but these are items that a child has worn, so please understand and purchase them. Type... Jumper skirt Size 100 Dog London Stylish Appliqué
