Bday Dress

I'm looking for my bday dress! Planning on having my bday on a local cruise ship. Thought it would be a little easier this year, the cruise provides a dinner buffet, drinks, live music/dj and whatever else is at their disclosure. So, I'm 6ft 1, a little busty, with a little bit of curves since I've lost weight. Here are some dresses that I've picked out, but need opinions. I wanted going to wear all black or black and gold, something that stands out, I think some of these dresses can be ordered in a different color, so its cool! Is luulla a good dress site? Toss some other sites for suggestions too I don't mind. Here's what I came up with and still looking!!!!
