I bought this for my 15cm silicone doll, but unfortunately, it was too small because the body and arms are the same size as a 22cm doll. It's lavender and very cute, so I hope someone can use it. The back is fully open with Velcro. The background yarn mat is not included. This is a sale of the dress only. The sales page states that it has been confirmed to fit Obitsu 11, Nendoroid Doll, Piconeemo P, STODOLL, YMY, and Picodo 9 dolls, but please understand that we cannot guarantee the fit.
