omg do not shell out $26 for that Bella Band .. go to the nearest fabric shop and get yourself a metre of spandex. It'll cost you about $8 and you can make more than one.
As for pregnancy jeans .. I had a style that I loved pre-preg and I went to the fabric store and bought a pregnancy panel - I cut out a U shaped piece in the front of my fave jeans (I have about 6 pair of the same style) and voila I had the best of both worlds.
I have to admit though - I only worked into my 7th month and I just got a 'pregnancy set' from the Sears catalogue. 5 stretchy pieces that all worked together.
It's just too much money to spend on a one time thing (if you only plan on having one like we did)
IMO Maternity clothes are a little bit revealing these days. I was never ashamed of my baby belly but I didn't want it on display either!
