Hi. So here's a little information.

Sizing: xs(4), s(6), m(8), l(10)

In general, chose your dress size based on your upper body. Almost all Filly dresses are forgiving through the hips and thighs. These patterns are based on my body and I ride a bike. If you have a question about sizing and your particular body, just ask me: emily@fillydesigns.com
