Yes they run one size small, but, these are very nice fitting joggers otherwise. I'm about 5' 6" just under 200 lbs, 3X is just right, (usually 2X) slightly loose, not tight. Mid rise, they fit below your natural waist and long enough, just below my ankles. They are soft, smooth and medium weight; they are perfect for me. Because of the fabric content, Body: 43% Rayon, 43% Polyester, 14% Cotton; Rib: 59% Rayon, 39% Polyester, 2% Spandex I will launder inside out, cold and very low dryer heat. I'm sure this will work fine :-)
After laundering as stated, they came out okay, after wearing, they pill a lot, especially around the waist :-( I do not recommend
