I am 57 135 lbs. I have wide hips, small waist. I got Light Denim, Medium. They fit perfectly on my waist and don't stick out in the back (the waist) and they are comfy too! I always have trouble with the pant/shorts waist sticking out in the back. Not with these! I got another pair which I am also ecstatic about! You guys! I mean, ladies! You need these shorts! I hope this company continues to make these exactly the way they are now.
