i NEED YOUR HELP!

With that being said...My roommate and friend Stephy is getting married and I NEED a dress to wear for her
 "Oh So Special" occasion!

I'm probably the most indecisive person on the planet {a quality I need to work on...} but until then...

Option 1

Option 2

{same dress, obv. different color}

Option 3

{concern: not dressy enough???}

Option 4

Option 5

Keep in mind there are going to be MANY single, attractive fellas at this wedding! :) Please vote on a dress for me! Thank you!
