The Perfect One

My friend and I are going shopping tonight after work for cocktail dresses to wear to our work Christmas Party. Each year I wear the same thing... a black dress. Yet, each year I have to spend money on a new one that I will probably wear just once (because I have to buy new for every single event I go to) and that looks pretty much just like the one I wore the year before... but for some reason in my mind is totally different and absolutely necessary!
