I need help

I'm attending a red carpet event and I have no stylist whatsoever. I'm horrible at shopping. I'm Just not gifted in that area at all. It's more overwhelming than anything. Especially for major events. Can somebody help me please ?? These are the dresses I have picked out. Are they ugly ?? Should I keep looking or will one of these work ??? Any extra online suggestions from some of you fabulous divas will help as well.
