I got this in navy for an early evening outdoor wedding. I am 5'6" 125ish LBS and got a medium but normally wear a small. It fit perfect and didn't ride up. The length was perfect. If you are my height or taller, I recommend ordering a size up from your normal size like I did so the length in the crotch and ankles works. Only challenge was bathroom breaks. The zipper is tiny and hard to get to on your own, especially after a couple glasses of champagne.
