Audition Technique

I do not understand showing up to an audition dressed for clubbing. At my first NYC audition, I showed up wearing dance pants and a fitted t-shirt. I thought it'd be important to be able to move. Wrong. Apparently it is more important to be femme. Heels. Skirts. Stockings. This was shocking to me. So heels, skirts, stockings it is. But must I really vamp it up with leggings and a low cut sweater that debatably functions as a dress and high heeled boots? Because I can do that. Or after a trip to H&M, I could do that. But are you serious?
