Advice for a career fair tomorrow

[Rena-san]

I want to go to a career fair tomorrow because I need a job. I was going to make copies of my Resume to hand out, because that is what you do at a career fair. But my problem is I don't know what name to put on my Resume. I haven't been able to change my legal name yet because I don't have enough money to pay the ridiculous $500 fee! Also, it takes about six months in the county I'm from.
Using my legal male name--which sadly is not a name like "Jamie" or "Jessie"-- wouldn't be too much of a problem except I'm at the point where I couldn't really present male in a professional sense: I have long hair, pierced ears, painted nails, budding breasts.
What should I do?

Or you could use your first initial and your last name. Then when they ask what to call you give them the gender title (Ms./Mr./etc) of your preference. You likely will have to come out on the paperwork later, but at least by that point they'll be interested.

I don't know what to wear tomorrow either. I don't have a dress suit yet. This is what I was thinking of wearing:
a plain white button up blouse
a grey vest top over it
a dark navy skirt that has quarter sized poka dots on it
Plain black heels
A bun or ponytail for hair
Light makeup
matte purple nail polish

Think that is professional enough? I don't know. I feel super nervous about this event for some reason. I'm debating not even going.
