Professional makeup for prom?

Hey guys, so prom is coming up and I’m thinking about getting my makeup done for prom?

I’ve set up an appointment for Sephora but I’m a bit worried. I’m a black girl and I’m afraid that I’ll get flashbacks or my foundation won’t be a correct match. Should I bring my own makeup or let them use there own?

Also I would do my makeup but I want fake eyelashes so I’m wondering if I could just do the 15 minuets of beauty and have them put on the fake eye lashes on me for free.
