Angelic Nina Maternity Adjuster Band Length 55cm Waist 72~ Very stretchy and expands An adjuster band is a band that you wear like a belly band to cover your stomach area when your jeans' zipper is open! Easy to put on! I thought it might be a hassle to go to the bathroom, but it's not a problem as you only need to unbutton two buttons. If you wear a long outer layer, your jeans' waistband won't be visible. Cost-effective as you don't need to buy new maternity wear!
