smoke-free home. this is stretchy. a v-neck tank top sweater material. Chico size 1 which is a medium or 8 to 10 in size. what's really pretty about this top, and different, is it has a crochet line that goes down to the v. it's about an inch thick. and it's a crochet type material. I love chicos and just sending out my closet a bit please check out my other items.
