It's hard to say what you'll need and how soon you'll need maternity clothes, each woman shows and grows differently. For me, in the first and second trimester, I could get away with pants with elastic stretch bands and shirts/tops a size larger. But eventually, later into the 2nd trimester, I had to buy maternity pants/tops. I bought basic black, tan and grey pants, and a couple pair of jeans/capris. I bought more tops, because there were such a great selection.
