I have another pair of these tights in a size S/M (which I should fit according to the size chart: I'm 5'3 and 118lbs), but they are too tight in the waist. I suppose they fit, but it creates an unflattering pinch at the waist under the leotard. I ordered these in M/L and they are just as tight as the S/M I already had. It's possible that there was a little more room in the legs, I suppose the M/L pair looked a little more opaque through the thighs thanks to the extra material, but I really needed just a little less pinch in the waist. I ended up returning these. The quality is great for the price though. The original S/M pair that I bought is still in use and has not ripped or torn.
