Learning to wear heels

Hi! I would love to begin dancing in those sexy pleaser heels I see, but I am a complete beginner to heels. I can walk in smaller heels alright, but these are a whole other level. Any tips or other advice for learning how to walk sexy and safely? Hey Veena... ever considered a "this is how to wear your new sexy heels" class? Lol... or do you have one and I just missed it? Thanks so much!!!
