Contains 4 adjustable, stretchy elastic extenders: BUTTON SET (1 SMALL AND 1 LARGE WAIST EXTENSION) + HOOK SET (1 SMALL AND 1 LARGE WAIST EXTENSION) Buying new clothes for just the few months of maternity can be expensive, ineffective and frankly, a time-sinking hassle. We could be reading books preparing for the arrival of the baby or spending time with soon-to-be big brothers and sisters. What if you could wear your existing pants, shorts and skirts by just buttoning an instant Waistband Extender to the button on your pant, short or skirt? You can save time and lots of money with this simple and comfortable solution. And the best part? The Waist Extender grows with your belly and lays gently on your stomach. The edges are sturdy cotton and the middle is a stretchy elastic so it can expand with your tummy. And because we know that the final months will be a bit difficult to cover with just extra stretch, this Waist Extension Set contains two size stretchers: a smaller and a larger. When your belly outgrows the shorter button waist extension, simply switch to the later months / last trimester, larger lengthener. Set Contains Two Sizes of Buttons and Hooks: Small (ideal for 1st and 2nd Trimester): Stretches from 4.75 to 7 inches Large (ideal for 2nd and 3nd Trimester): Stretches from 6 to 10.5 inches WARNING!
