Is it all right to have my hair consultation when I'm not sure of the hairstyle I want, or what kind of ornamentation/veil I'd like in my hair?

Absolutely.  Rosemarie is happy to demonstrate “drafts” of several different hairstyles and offer recommendations on which works best with your facial features and gown.  She’ll also show you how your hair would look with a tiara, headband, comb, veil, etc., so you can decide what you want to use on the big day.
