Brooks Brothers blue striped knit top, Women's S/M (runs small)

This is a beautiful Brooks Brothers blue striped light-weight knit sweater, or top in excellent condition. The size is a Women's medium (M on the tag), but it runs small. The fabric is 100% rayon/viscose. It is airy, stretchy, and comfortable, but the real size is small in my opinion. Measurements (flat): Length- 27 inches Width-- from underarm to underarm is 13 1/2 inches From a smoke free home
