If you are, or if you know someone that is expecting, than you need to check out The Belly Bra. You can find it at www.bellybra.com
I got it, and it saved me unending backache, and it made my life so much easier. Basically what it does is, it helps you carry your bump. It looks for all intents and purposes like a vest, but it has a really secure strong band at the hem, and that is what works to help carry your bump. It's designed for the third trimester, when being pregnant gets more and more uncomfortable.
True enough it's not the most cost effective solution, as you can get belly braces for less than half the price, but I can guarantee you that they don't work half as effectively. It is available in four colours Black, White, Tan and a Black Lace effect.
If your pregnant, you should get it, if you know somone who is expecting, get it for them, they really will be extremely grafeful!
