This is a back-open cut tunic from American Holic. It's hard to see in the picture, but it has cutwork on the back, so a little bit of your upper back near the shoulders will show. The manufacturer's size is M, but it's a large fit, so it feels like a size L (^_^;) I only wore it once as pajamas on a trip, but please refrain from purchasing if you are concerned about wrinkles from being folded. m(__)m I will fold it up small and ship it in a Takkyubin Compact dedicated box! Flat measurements: Width approx. 62cm, Length approx. 70cm *Please read the profile before considering a purchase.
