Dresses to make heads turn

I've got a wedding in a couple weeks and I haven't the foggiest what to wear. Definitely want to wear a dress, but I definitely don't want to wear all white or all black. Here's some possibilities:

Lux Hollywood Dress $29.99 from Urban Outfitters; Isaac Mizrahi for Target Bateau Neck Pleated Dress $39.99 from Amazon.com;
