i bought the iris blouse and skinny jeans today at madewell. i'm still iffy on the blouse. the fit is very roomy except in the shoulders, and the silk wrinkles easily. the jeans fit surprisingly well, although i'm not completely comfortable wearing something with such a high waist. will post photos tomorrow to give you a sense of how they fit.
i'm wearing the small. i think i'm going to return it because of the wrinkling. the jeans don't look as high-waisted as they feel. i'm a bit ambivalent about both pieces.
