What should I wear?!

What should I wear? I'm spending New Year's Eve with my two best friends and their husbands. There are five of us in the big house of one of them. And because the opportunities to dress up have been so rare lately, we decided to have a sexy-motto-evening and really dress up. But what exactly should I wear !? How I would love to have someone tell me what to wear! I have already put together a part. I'll put on my black pumps with which I can dance too. I wear the leather cuffs as bracelets and one of my chokers and leash as a necklace. I'll wear the blindfold like a headband and hold my hair back with it. Last but not least, I am wearing pearl panties, so that the evening is guaranteed to be exciting for me! But what do I wear to it !? A black velvet catsuit? A knee-length bodycon dress? Just a short skirt and a semi-transparent blouse with a bra? The skin-tight pencil skirt that goes a little over my knee? An evening dress with a high slit and a deep back? The flowing, cream-colored chiffon skirt? What would you have me wear tonight !? And please don't say: Nothing. I have to wear something! Please help me! Kisses Annika.
