For starters I'm 5'4" and around 180 lbs (36F, usually size L on the bottom) and I purchased the size Large. I was very impressed with these shorts y'all! The medium wash is pretty dark which I love, looks just like the pic, and I won't lie I didn't think they were going to fit when I was trying them on but they fit really well. They're snug, but not uncomfortable, and when I thought they wouldn't stretch enough for me to button them, they did. Not only that, but I can actually sit down in these and not feel like they're going to cut me in half like some others I've tried in an attempt to find a pair that fit my thighs + butt + hips + waist all in one.
