Memoi Spot on Basics cotton sweater tights are model SP-3405. These ribbed cotton tights are very economical. Regarding sizing, they run a little bigger than some other brands of cotton tights. I have found the adult sizes Petite, Average, and Tall run a bit big in the foot. If you have a foot smaller than size 7 or 7 1/2 this product might be too big in the adult sizes. To get another idea of the sizing, I know that a girl/woman who is 5'4" and about 115 lbs. can fit comfortably into the size Average after they go into the dryer but that size can accommodate someone that weighs more. 75% cotton, 25% polyester, 2% spandex
