This is a blouse from apres jours, a brand exclusive to ZOZOTOWN. It is no longer sold. The color is ivory. The size is F, a free size. Made of 100% polyester (88% nylon, 12% polyurethane for the lace part only) It's long-sleeved, but the fabric is thin, so an inner layer is required, but it can be worn even in midsummer. The attached ribbon is removable.
