I’m between L/XL and opted for the L, as I wanted a more snug fit and knew the fabric would ease with time. For reference, I’m 5’10, 230lbs and my measurements fluctuate between waist 37-39” and hip 47-50”. I’ve always had large, muscular thighs and these fit perfect: great length, a comfortable amount of compression in the waistband, and the fabric is to die for. I will note I was terrified I was going to bust the seams the first time I pulled them on, but they’re sturdy!! Highly recommend
