I purchased this for my child's entrance ceremony while I was pregnant with twins. The waist is elastic, and it's comfortable to wear. It also has a nursing opening. For reference, it fit me perfectly at 157cm tall. I haven't used it much, but please understand that this is a used item. Please comment if you have any questions. -------About Shipping------- I will ship it folded compactly. Please purchase only if you understand this.
