This is a plushie outfit for 10-12 cm plushies. It fits the Project Sekai Petit Nui plushies. (See image 3; the plushie is not included.) I've used it a few times. There are no noticeable stains, but there's a possibility I've missed something. I purchased this as a handmade item, so there may be some loose threads. The fabric attracts dust easily. Please refrain from purchasing if you are concerned about these points.
