If you are looking for a change from the typical maternity selection, check out this store. They carry the more high end, upscale maternity lines. While you will pay more obviously for these clothes, they do in general wear a little better and last longer than the cheaper brands.
The staff is very nice and helpful and the selection is great. They also have a website online that you can check out.
So if you want to look nice your entire pregnancy, definitely shop here and see what they have.
