Boudoir Shoot Soon! Help!

I was selected out of hundreds to be an ambassador for a boudoir photography company. I never win anything so this is HUGE for me!

They require me to do an hair and makeup. I suck at both!! Any makeup products and tutorials you can recommend?

Maybe a makeup style you think would compliment a boudoir shoot?

I also need help! Idk what to get that is used for contouring! Idk how to match for my skin tone.
