But it wasn't really buried, what I discovered is that Asos, a European fast fashion source has a HUGE selection of maternity clothes plus free shipping both ways, so you can experiment with styles and sizes without feeling like you are wasting money. I'm pretty sure it doesn't get much better than this!
