This Gap fisher or fisherman knit turtleneck sweater is a women's size XS and fits this usual M or S Posher perfectly (so IMO I think it runs roomy). It measures 18" un-stretched across at the armpits. Please see photos for additional measurements. This cotton cable knit sweater is in great used condition. I can find NO pulls, stains, holes, stretched-out parts, or any signs of wear. To me, it seems new or NWOT, but I bought it at a resale boutique so cannot be sure. The tag says the color is milk. I'd call it white, but not optic or bright white. If you need additional measurements or otherwise have questions, please leave me a comment and I'll get back to you ASAP. Thank you!
