MUJI Dark blue denim blazer jacket, 100% cotton, button closure, with two front pockets. - Pockets: Two front pockets - Design: Button closure, with collar Length from the neckline: 63 cm Width: 48 cm Sleeve length: 57 cm Size...S Soft and lightweight. It's stylish to roll up the sleeves and show the inner layer. Although it's S size, it's a bit oversized, so even those who wear M size can wear it casually. You can wear it cutely in spring and autumn, both casually and dressy. Because it has a collar, I think it will be useful for semi-formal occasions. Please read the profile before purchasing.
