I am 130 pounds and 5'4''. I ordered mediums because thats the size I ALWAYS wear, but these were way too big! They were a good 3 inches too long. In addition, there was too much room around the waist. I ended up giving them to my brother. But they're a good quality. I wish they had fit:/ There's zippers on the calves that make putting on your boots easy. Perfect amount of insulation. I wish they had sizing information when ordering, hope this helps.
