I believe this is a collaboration or anniversary limited edition dress from SM2. It has an antique lace-like collar and a sailor-style back. I fell in love with it and bought it right away＾＾ I had planned to wear it and pre-washed it, but it's been in storage, so I'm putting it up for sale. Size: Length: Approximately 104cm from shoulder Width: Approximately 60cm underarm The color is sumi-kuro (charcoal black), so I think it can be worn without looking too heavy. It opens with buttons in the front, so it can be worn like a cardigan. It's also cute to unbutton a few buttons at the bottom and peek out a petticoat. I will fold it as small as possible for shipping. If it's over 60 size, I'd like to ship via Eco-Mercari, so if you're okay with that, please leave a comment＾＾ Please understand that this is a home-stored item before purchasing. Thank you very much m(_ _)m
