It's a size M. AG by aquagirl Pleated Dress I bought it because it looked like the jacket photo for Nogizaka46's "Sorezore no Isu" (see the last photo for reference). I think it can also be used for invitations to weddings and other events. There are wrinkles from storage. I used it once at a live concert. For those who are fans of Nogizaka, please consider it. - Brand: AG - Color: Blue - Design: Pleated skirt - Style: Casual Thank you for looking.
