Please excuse her after nap grumpy face. She does like them, and has worn these every week since I made them. The pants are a soft cotton velour with ribknit waist, made from the Ottobre 1/08 "jump" sweatpants pattern. The top is made from the Farbenmix Quiara top pattern, which I totally love. I have made this top multiple times now, and it comes out great each and every time.
