after reading the reviews, i was heavily debating between getting a small or a medium because i weigh 127 lbs, and another poster was way below that, got a small, and it looked just right on her! however, i saw other reviews that wore medium and were a different weight from me, and it also looked fine! soooo i just decided to measure myself and go according to the chart. my hips are 35 inches, so i went for a small, which is recommended for a 36 hip. it literally is perfect and is not necessarily very cheeky actually! it is not tight to the point where my sides are bulging out of them, but they fit to skin. although it is low-rise, it is a comfortable length :) just know that whatever your hips are, follow that sizing and do NOT base it on your weight!!! i personally do not think they run small at all if you go according to the size chart and not based on other brands' sizing.
