Plus Size Maternity Bridesmaid Dresses?

T

My best friend of 21 years is getting married in June and has asked me to be in her wedding party. I’ll be 30 weeks by that point and I haven’t told her I’m pregnant yet (waiting until after the time I had a miscarriage). I’m plus size already (size 20-22) and can only imagine how big I’ll be by that point. The other bridesmaid is very thin so I’m struggling to find a dress that comes in both our sizes. On top of that, her fiancé is Chinese American and there are some superstitions about pregnant bridesmaids being bad luck so I’m trying not to look THE MOST PREGNANT. She hasn’t finalized the color yet.

I’ve checked David’s Bridal but the options are limited. Do you know of any stores where I can find plus size maternity dresses that are also available in smaller sizes? Thank you!
