I sized up one size so it wouldn't be tight and it was actually a little big. It doesn't come with shorts so you need to get a pair of bike shorts to put under. The material was cool and it was 92 degrees on that golf day and the dress was perfect. Light weight enough to breath and didn't stick to me for 18 holes. I would reorder and recommend Mary Square for quality products. This was my first purchase but won't be my last!
