Okay. I think shoes are a similar approach to the dresses. I think neutral shoes look great with bright-colored dresses, and I think that because i saw this picture:
Also, I feel much better about asking you all to get shoes that could be purchased at your favorite local shoe shop (or secondhand store), instead of dropping $50 for custom-dyed shoes at David's Bridal.
I would recommend a pair of off-white or white shoes (my dress is a creamy ivory, and a bright white might stand out in a weird way). Your call on heels vs. flats... we're all different heights anyway (as are the boys), so I don't think a couple inches would make any sort of difference.
I'm planning on getting each of you a pair of fancy flip-flops that match the color of your dress, so that if you do wear heels, they won't be killing you on the dance floor or while we're drinking wine before the ceremony. (Because that will be happening).
Welp, that's about it.Let me know if you have any questions!
