Monday's Child in Alexandria has beautiful, classic ones.

Try the Lemon Drop in Chevy Chase or Beyda's Lad & Lassie in Bethesda.

Consignment shops are another possibility.

Burlington Coat Factory

I've always had luck at stores like Marshall's, TJMaxx, or Nordstrom Rack. Give them a try.

I would hit a mall with dept stores and a Strasbourg children because they sell very dressy kids clothes.

I found mine at JC Penney. I will say it was around easter so probably a better selection, but they had something cute and relatively inexpensive that worked for us.

I would just go to Lord & Taylor:

David's Bridal.

Wondering if there's anywhere good to look for flower girl dresses in the area? I know I can order them online, but that makes me a bit nervous about sizing / colors / etc. And the weddings in 2.5 weeks, so quick turn around is key.

Thanks!
