The size is M, and it should fit those who usually wear S to M sizes. The mannequin used for the photos is a size M. Length: 50cm Width (underarm): 44cm Shoulder width: 37.5cm Armhole: 36cm Sleeve length: 51.5cm Hem width: 40cm Material: 100% cotton The fabric is not flimsy; it's a sturdy material. It appears to be free of noticeable stains, dirt, or tears, but there is a sense of wear and tear characteristic of the fabric, so please only purchase if you are comfortable with vintage or used clothing. The color is a slightly more subdued pink with a purple logo than in the photos. ★The skirt and pants shown in the photos are listed separately. Please ask any questions you may have before purchasing. I also have various other items for sale, including tops, bottoms, shoes, hats, and accessories.
