Used once for an event. Innerwear is not included ✗ The wig is made by Assist. A plastic bottle is used. It is removable. The outfit is made of linen fabric. Since it is handmade, the edges are not perfectly finished. Please refrain from purchasing if you are looking for perfection. Made to fit a 165cm tall person. I think it's about M to L size. There is elastic on both sides, and the obi is sewn to the back, so you can wear it just by tying the front. The hood has a hole, so you can put it on just by passing your ponytail through it. Everything will be put in a waterproof bag and shipped together. Instant purchase is available.
