My Little Black Dress obsession

Ahhhhhh!!!!......I have been dreaming of little black dresses. I feel like I see them everywhere (billboards, magazines, stores, commercials, TV shows, etc...).

I am dreaming of owning this very different silhouette by Diane Von Furstenberg. I always thought that the first thing that I would buy from DVF would be a classic wrap dress.
But, I'm not so sure anymore since I literally can't stop thinking about this dress. I want to go to SAKS and try it on before I make any sudden purchases. I feel like there is a 50/50 chance of success/failure (no gray area or in betweens).
However, on my many internet searches I found these 2 other dresses that I also like very much.

What is a fashionista to do?
	Try on all dresses, run the risk of loving them all, and buying them all.
	Try on all the dresses and buy only one dress (no exceptions or excuses).
	Do nothing, buy nothing, stop thinking about it and ignore the feelings.

The objective side of my brain reassures me that I don't need anything, while my creative side tells me to buy everything.
