NWT aerie navy crew neck soft lightweight sweater

NWT aerie soft navy crew neck lightweight sweater. Lots of stretch because of open weave but looks better not stretched. Would need a cami or pretty bra underneath. Although the tag says medium, in my opinion it fits a size small/medium stretched. From year 2011 as indicated on the tag but I didn’t wear it/it is in new condition). Fabric composition as shown on tag in pictures (acrylic/wool/mohair/nylon).
