Tibi Winslow Sunmer Sweatpants are made of mid-weight French terry, covered elastic waistband, slant hip pockets, shell 100% cotton, snaps with placket to adjust the length in the back of the sweatpants. In my opinion, fit is oversized and slouchy as it looks on the model. They are not as bright of white as in the stock photos, I have never used any sort of whitening product on them overall good condition. Cold water washed, lined dry only. worn several times.
