What to wear to a party

You know when you try on like 20 different outfits, but you can't decide what to wear? And at some point, you lose perspective and start trying on old high school clothes from the back of your closet, or adding accessories that aren't even really meant to be worn that way, like using a scarf as a belt?

I understand the dilemma she was going through before she left the house, but I'm not convinced that this outfit was the best of all possible options.
