Here's a clever device that doesn't need to be powered up; won't play music but could quickly become your favorite invention if you're pregnant. Forget the maternity jeans and add the b-buckle to your favorite designer jeans. This way, you can wear all your pants throughout the entire 9 months. A miracle.

These wardrobe savers come in 3 adjustments for the perfect fit and you pick your size based on your pre-pregnancy size : small fits zero to 4, medium fits 6 to 8, large fits 10 to 12

If you're Stateside, you can order them directly from the Californian company, b-buckles for $22. Check out the video on the site,while you're there.

So far, they're available in the UK at Boutique To You for £14.99.
