This is a knit top to be worn over a light blue V-neck leotard. It has an opening in the back. The pattern shows through when worn, making it very cute. See photo 4. I stopped using it soon after purchasing it, so it has only been worn a few times. - Size: 140-150 - Material: 95% nylon, 5% polyurethane - Design: V-neck, opening in the back - Color: Light blue Thank you for looking.
