1920's Bridesmaid Dresses

Renttherunway.com they have some gorge ones you can rent!

Not sure what your budget is but check out adrianna pappell, aidan mattox, and sue wong.

what's the biggest size you need?

I've seen some really pretty beaded dresses at macy's, dillard's and nordstrom. designer adrianna papell has some really pretty ones.

Have you looked at Sue Wong's gowns/dresses? She has a strong '20s influence... they're not cheap (at all) but they're works of art

Not sure if you or your BMs are paying for the dress, but this route didn't work for me budget wise Beaded dresses are usually pricey. An alternative is to incorporate 1920's elements like having them wear feathers in their hairpieces or bouquets, beaded headbands, or art deco style jewelry.

My girls are paying for their own dress. I found one at David's bridal that would have worked but it's no longer available =/ The largest size I need is between 18 and 20. All the girls are tall except one. I hate the fake 1920s looking dresses. I want a more classy wedding party. But I don't want to break the bank in the process.
