Hi there!

i used my belly belt all through my pregnancy. I lOVE them! they have since been doing the rounds with my pg friends...

you get a pack with button ones and ones with clips (to use on all kinds of pants). they come in 2 sizes and the larger size has different fabric swatches to hide gaps etc. i found that i only really used the small size as it did the job right up until i hit the ginormous stage of 36 weeks (where basically nothing is comfy LOL!).

i got mine from a maternity store for about $30...

HTH
