I hardly ever wore kimono's when I wasn't pregnant but they have been one of my pregnancy staples since I have started getting bigger in my stomach, arms...well everywhere really. Check out other ways I have worn kimono's here and here.
Dresses are also a no-brainer maternity staple. I couldn't have survived this far into my pregnancy (21 weeks and counting) without them. Great news is most are actually just a size up from my regular non-maternity sizing so hopefully I will still be able to get some use out of them in the years to come.
