I bought this leotard for my four year old daughter. I got her the 6x-7 size as recommended in the sizing chart. Although she is tall for her age, she is pretty well proportioned. The leotard is a little baggy in the chest, but barely comes up high enough on her to cover her. There is no way the straps are going to stay up when she's trying to dance! If I had ordered a smaller size, it definitely would not cover her up. It just seems to be designed for a shorter, wider child. However, the fabric is very soft.
This is a leotard with great value, however, it's best for younger children. The fabric is good. Although it's full front lining (with the same material as the leotard), it's still a little see-through.
