Wedding Hair Style

Question...

How soon should I schedule a trial run with my hair stylist? I haven't even picked a stylist yet, but it's on my list of things to do in January. I was thinking that I might schedule a rehearsal hair and makeup appointment in the beginning of March...Is that too early?

By the way, I'm still completely indecisive about the hairstyle that I want. I'm pretty sure I'll be doing long waves with a floral hair piece, but I like the messy updos too!
