What to wear on valentines Date???

I have been browsing online to get an idea if what should I be wearing on my Valentines Date??? I don't have any clue. I would like to wear a dress but I can't decide to what color I should go to??? Would it be red, black, blue, white, purple or tangerine???

I have been so much time browsing on the websites of express, bebe, victoria secrets, and, guess but I still have a hard time deciding. What would I wear??? Whew!!! I am considering the prices as well, and I ain't so sure if the dress would good on me. I truly hate shopping online. I could easily decide if I see the dresses in person and I could be able to fit them on. Shopping online is driving me nuts!!!

They said you could never go wrong with a little black dress, but what kind of black dress should I pick??? There are tons of them!!! I don't have any idea what would my man wear and I wanted to match with whatever he is going to wear...I like it when it matches. I just think it's cute. Haha!

I kinda like this one from Guess, but I think it is too over price I am not sure it's worth the $$$ though...whew!!!
