Blogilates long sleeve top blue gray Size M NWT

This brand new Blogilates top in blue gray is a size medium. It has a beautiful tie in the back and a square neck. Stretchy material with thumb holes. Ruched sides. Perfect for exercising in style! This top is brand new, I only tried it on but the tag did come off. For some reason the tag says size Small even though the top says size medium. It does feel like a medium which is why I'm selling it, I bought it because the attached tag said small which was not accurate.
