I've got an interview at Fresh Market tomorrow?

It's my first interview ever.
So naturally, I'm nervous beyond belief.
[And it didn't help that when they called me while I was on the bus Thursday, with people screaming obscenities and such in the background.]

Also, I don't have any "dress clothes" except for a pair of pin stripe pants, and a couple solid colored t-shirts. [yes, it's that bad.]

Any advice on what I should do/say?
What questions I should expect?

4get about the call on the bus, they should understand that that's out ur hands.
Wear ur pin stripe pants n a nice solid color blouse. Do NOT wear sneakers under any circumstances...lol. Not 2 much jewelry or 2 much make-up n turn OFF ur cell at the interview.
B urself n NEVER EVER cross ur arms. Look at the interviewer right on the eye n shake ur hand firmly. He/she will ask u if u had previous experience on that field. Say the truth but also tell them that u've worked doing baby-sitting n that requiered lots of responsability.
Ask them if that position comes w/ benefits n how much does it pays. Do they have a union, Holidays, etc, etc.
Good luck tomorrow n knock them down!
PS: try 2 b there 15 minutes before the interview.

Try to be relaxed. Don't worry about the clothes make sure your clean and hair is combed. Not to much make up, none is better. Don't try to out smart the interviewer. Don't go in with a plan, freelancing it is better. Spend a little time at the market just to get a feel for the place. Good Luck
