I like things coordinated, but not identical. For my bridesmaids, I gave them my parameters (marine, floor length) and let them pick the gown they felt most confident in. My maids all picked ones with decorative necklines, so I got them matching earrings to tie their looks together. Since the dresses can take a while to come in, I was getting a little worried that one of my maids hadn't purchased hers yet.
However, I also didn't want to be a bridezilla and keep nagging her. When Facebook so kindly informed me that David's Bridal was having a sale, I casually passed that information on to her and to my mom.
They went shopping over the weekend and she was able to order the one she loved for $50! (Regularly close to $200.) I'm filled with joy for her because I know finances can be tight (for all of us) and didn't want my day to be a huge burden.
David's Bridal quoted her way too much for alterations, so I told her we'd do much better closer to the wedding.
I get to check "bridesmaids dresses ordered" off my to-do list (and that brings me joy).
