I need a lot of help. Please no one comment if you have anything negative to say.

I haven't done an amateur night for like a cash prize winning but I have really wanted to.

I have tried out in front of other staff at a club before, and even though I can't dance lol they said they could teach me or it's really all about flirting to make money (and they didn't think I would have a issue with that because I have a attractive hourglass figure) and would hire me but I walked away. I've been disappointed in myself because I've just put myself in more debt struggling hard, trying to work 3 jobs since I've turned 18 and etc. (I am in my 20s now)

I know there are requirements on certain clothes or heels. So can you help me out, what are they and where do you get your work clothes??
