You probably wouldn't think to wear blue shoes as your something blue, but fun-loving brides are making this a new, modern tradition. What could be cuter than having some awesome blue peep-toe heels peeking out from underneath your wedding dress?
If the blue shoes are too daring for you, you could always just paint your toenails blue. Although not quite as daring, it's still a fun way to incorporate a nontraditional accent as part of your wedding wardrobe. Go with baby blue to match your garter, or get shocking Caribbean lacquer to complement the ocean -- especially if your honeymoon destination is in a tropical locale!
