Prom dress opinions needed!?

I love the last one! It would give you great support. I wouldn't get a strapless dress because they give no support and if you trying to make the most of your ets strapless is not the way to go (unless you can pull them off! I don't know!) Also the 1st dress would be slimming because it's in black! If you could get the last dress in black that would be perfect!!
