I'm thinking about buying convertible dress for my BMs. Has anyone deal with these company, two birds or henkaa before? They have similar dresses but the price is different...henkaa is cheaper than two birds. And also short or long dress, which one is preferable for the beach wedding? http://www.twobirdsbridesmaid.ca/dress/classic http://www.henkaa.com/convertible-dresses/sakura
