I’m 5’3”, 155 lbs and i usually wear a medium. I bought a large and it’s still a pretty tight fit. They don’t have much stretch and the fabric is honestly not that comfortable. They’re definitely not made for anyone with a booty because for as much as I can pull them up in the front I can barely get them up in the back. So they ride up a LOT in the front and feel saggy in the back. I had these on for 10 minutes, started squatting and felt like I had to stop because they slid down so much. The only reason I gave them 3 stars was because the price is reasonable for what they are and the fact that you get 2 pairs. I just expected them to last more than 10 minutes into my first workout.
