The size is S, but it would be a good fit for those who usually wear S to M. The mannequin is a size M. Length: 66.5cm Width (underarm): 48.5cm Shoulder width: 42.5cm Sleeve length: 55cm Hem width: 54cm Material: 100% Polyester This is an elegant blue striped shirt. The sleeves are puffy and have elastic, so you can push them up to your elbows for a balloon sleeve look. The ruffles flutter and look cute when you walk. There are no noticeable stains, dirt, or tears. The color is a bit lighter than in the photos, closer to the blue in the second photo. This is a GU item. ★ I also have other items for sale, such as shirts, Uniqlo items, bottoms, shoes, hats, and accessories.
