This is a Mercuryduo blouse with frill sleeves. I wore it once, but it didn't suit me, so I'm selling it. It's a white flared sleeve shirt with a ribbon, and it's cute. Made with rayon, the fabric is light and feels smooth. The ribbon and collar are removable, making it versatile. It's a sweet item, but I think it's perfect for office casual wear. The buttons are hidden. It's labeled as F size, but it feels like a size M when worn. The frill part has plenty of room, so it's a design that's okay even if you're concerned about your upper arms. The color is a regular white with less yellow. There are no noticeable stains. When shipping, I will fold it, so please be aware of wrinkles. I plan to ship via Nekopos or compact.
