dajrekshn, I don't know if you've already gone to the wedding or not, but I don't think that dress is trashy at all! It's a pet peeve of mine when people are afraid of showing-up the bride and instead do the polar opposite and wear something fairly dour/conservative (for whatever reason, most of the women I know do this). I see so much black and grey at weddings. Weddings should be fun! And unless you're wearing a gorgeous white dress, you're not going to distract from the bride! haha. But yeah, in short, I like your dress alot. Great color, not too short, looks festive, etc. And as far as shoes are concerned, I'd just make sure you bring something you'll be comfortable in for several hours, and comfortable dancing in.
