NPR: Wedding attire....?

ali2005jason

So I have a wedding to go to in two months. It's for a really good childhood friend. She is doing fall colors and I'm thinking I want to wear something with brown. I would like to have mine and Rory's dress coordinate and then somehow coordinate DH and Caleb too. I really like this dress for Rory but of course it doesn't come in her size. I like the idea of brown with a brighter color.

Would that be wrong for a fall wedding? I would like to find something like this for me too....have you seen anything? I have a bigger butt and hips and wear a size 12. Thanks for your help ladies!!!

ETA: I would like to spend under or around $30 for mine and under $20 for Rory's. TIA!
