Save your jeans and save your money with these super nifty pant expanders. The B Buckles will allow your cool jeans to take you through to almost the end of the pregnancy, I guess it all depends on how big you get. They do come in different sizes so you could potentially go all the way through if you don’t get too big. You just loop this through your jeans button and you’ve got yourself some added girth! They come in different designs so you can show off the belt line. I had ones that were not covered so it was kind of embarrassing when the rubber elastic with the button would show when my shirt rides up. These allow you to wear hot mama tube tops and tanks to show off your belly! At Polka Dot Platypus for $22.
