Nervous about getting my haircut. What should I do?

I’ve been growing my hair out for two years after a bad cut (stylist put in layers galore). I’ve mostly worn it up because I’ve been growing out the layers (have longer layers now). I would like to get a proper cut/style, but I have no idea what I want, nor what would suite me. I have an appt. for a consultation this week. What should I say to the stylist? This is a different stylist, by the way.
