I'm 5'7 135 lbs, bought a size medium in these hybya shorts. I usually wear a size 4 or 6. I loved the feel of the material but the sizing is extremely way off! They are huge to say the least. They are short which I didn't mind but the waistline was like a size 16-18 , they were falling off me and I could barely keep them up with the draw string. I carried them back to the store and all the mediums were that size. The sales lady was surprised by the sizing as well and agreed with me. There were no small available for me to try on but I'm thinking they are huge too. I would not buy these online. If you see them online in the store and they look like they may fit you then that's the only way I'd buy them. Don't pay any shipping charges on these! Not worth it!
