When I was only a few months pregnant and just starting to show, I wandered into the Babystyle store at our local mall. I noticed right away that they had really cute stuff, but it was too expensive for my budget. I happened to pick up a pair of of jeans that had been marked way down ($12.99 from $80, I think). They were my size and I couldn't pass up that good of a deal, so I bought them. They became my favorite maternity jeans.
They didn't look at all maternity jeans - no big belly pouch, no fat elastic waistband. The denim was stretchy and they were cut to fit under your stomach. They looked like a normal pair of jeans I would wear if I wasn't pregnant. I used to jokingly call them my moviestar jeans, because of how well they fit. I wore them throughout most of my pregnancy. I didn't have to give them up until the last month when NOTHING fit. They were comfortable and they washed well. They still look good after lots of wear and lots of washing.
I wish these jeans weren't so expensive, but if you can find a deal like I did or if they fit into your budget, I really reccommend them. It was great to have a pair of jeans that I really felt good in, even as I got bigger and bigger. Every girl should have a stylish pair of jeans, even when she's expecting!
