These are great underwear for wearing to bed or sitting around the house on PJ Day. They do not sit on the waist under Jeans or Dress pants as there is no elastic on the waist area. I however purchased 4 prs. and then went back and ordered another 10 pairs for a comfy sleep during the hot summer nights. I ordered sz. Med. I`m 5 ft. 2.....110 lbs. curvy. The fit was good.
