well, I can't help you with that, but I can offer a less permanent and more cost effective solution!The Belly Belt
I had one with ds and ended up making them for my friends because they're ridiculously simple. If you sew, all you'll need is two 15''x15'' squares of fabric, two bands of elastic (one 3'', one 5''), and a couple of buttons.
If you DON'T sew, and don't want to pay the $16 dollars, or whatever they want for them, I'd be happy to make one for you.
They work well! I remember wearing one in my pre-preggo pants at about 8 months, so disregard what they say about early - mid pregnancy.
