EUC Karen Millen Cowgirl western fitted shirt XS

Excellent preowned condition. Karen Millen cowgirl western style snap up shirt blouse. Denim blue. Fitted and very flattering. No where NEAR a size 12 that it says on the tag so I measured it so you can compare it to something you own. Top snap is not supposed to close and is there for detailing. Laying flat the pit to pit measures 17” across. The Length is 22” and the middle area is 16” across. The arm opening is 6” across. No Stretch. I would say this is more a Small or X-Small. #Q-7
