I purchased this new and have only worn it a few times. The waist has an adjustable elastic. *Please understand that this item is stored at home and has been inspected by a non-professional. If you are sensitive to smells, please refrain from purchasing, as I do not smoke or have pets, but there may be some home odors. *I am careful, but please forgive any oversights. I think it's relatively clean since I've only worn it a few times, but please refrain from purchasing if you are nervous, as it is a home-stored item. ◎ I will fold and compress it to fit the Nekopos size. ◎ I may change the shipping method to Yu-Yu Mercari delivery.
