The waist is made of elastic and measures approximately 32cm! I've never worn it, and it's been stored in my closet. ^ ^ I don't think I'll wear it, so I'm selling it! I'm 162cm tall, and when I wear it pulled up to just above my belly button, the length reaches my ankles! Please check the photos for details before considering a purchase! This is a used item, so if you buy it immediately, you are agreeing to everything, and I ask that you refrain from complaints or negative feedback after the purchase m(._.)m Please comment if you'd like to negotiate the price (*^^*)
