Make up for the wedding

I had an e-mail exchange with my make up person asking her if I should have any make up on hand with me in case I'll need touch ups and she said that since no make up will hold I should not spend money on anything other then what I have, it should be enought for touch ups.

Now I am really worried. I don't wear make up on daily basis and to be honest a bit freaked out and considering changing her, but I am only 10 days away from the wedding.

Please help!!
