This is a guaranteed authentic item purchased by myself on Royal Flash Online. The size is a popular L size. It's a beautiful item, worn once for a short time with an undershirt. However, it is a used item, so please refrain from purchasing if you are nervous about it. It's sold out immediately in all stores, so if you want to buy it at a reasonable price, please do! Length 72.5 Shoulder width 56.5 Sleeve length 21 Bust 121 [Refer to the Royal Flash website]
