Congratulations on your date! How exciting!

All of those dresses are beautiful, and I am sure that no matter which one you choose, you will look stunning.

Perhaps this may help: where is your date going to be? Those dresses all have very different attitudes. The first is light, flirty and fun: if you are going to be outdoors, for example, I would suggest that one, or going for coffee. If you were going to a fancy restaurant, or dancing, for example, I would choose the third, as it is sleek and sexy. If you were going to the movies or dinner, and just wanted to look bold and beautiful, I'd choose the second.

Just wear whatever feels best. It'll look great, no matter what.
