I usually wear size 11, but I feel it's a bit small, so I've listed it as a size M. The lace on the front and hem is beautiful. The center back has box pleats, making it roomy. This blouse has a luxurious feel with lace and sparkling pearl buttons. It can be worn in various situations such as graduation ceremonies, entrance ceremonies, school events, and commuting to work. Shoulder width: 36 cm Length: 51 cm Width: 52 cm Sleeve length: 54 cm All measurements are approximate and taken flat. 100% polyester. Purchased at Kintetsu Department Store.
