Its a Crisis....

I have mooting on monday, for the none law student, it is a staged court appeal where we have to be either the appellant or respondent and argue your case in court. The problem is I am no where near where I would like to be,and that is not worrying me, what I am stressing about is my outfit. We have to look like proper lawyers, that in my understanding mean, fitted dress and amazing stilettos. My worry right now is that, I got the dress (and yes surprisingly its not new.. i bought it some months ago whiles shopping with my mother but never had the chance to wear it until now) but all my shoes are too sexy to be lawyer shoes therefore I need a new one. The main point of my agony is that, I made a promise, for forty days not buy anything new for the sake of buying unless its important. So now, I am stuck between the two, what should I do. But would you not say shoes to match a dress is urgently important. Someone help me, if I buy the new shoe, do I break my Lent or whatever its called??

i absolutely love this dress
