OMG, bwahahaha! That's fantastic! Thanks, shesus
When we got married my two battle buddies/witnesses barely had time to change out of their BDU's, lol. I think they both just wore jeans and a t-shirt. If we would've had a bigger ceremony I probably would've gone to Macy's for the bridesmaid's dresses, too. Their in-store and online selection is pretty impressive, and they're not too expensive. However, I'm not very particular, so perhaps you shouldn't take my advice on this matter
Here's my $100 wedding dress (and $20 shoes) straight from Macy's:
Good luck with your dress-hunt! I hope your wedding is everything you are dreaming it will be, and more!
