What to wear for bridal styling

Hey y’all! I have a friend who has asked me to do her hair for her wedding tomorrow. She is wanting to keep her theme and style very classic elegance. My question is what should I wear for doing her hair? I will be at her house at about 5:45 in the morning (her wedding is at noon it’s an hour drive to the venue) so I imagine there will be photos being taken throughout the whole process. My thing is, I’ve always been of the belief that you never wear black, red, or white to a wedding. But as a stylist, of course, most of what I own is black. So do I dress in black to blend into the background or do I follow the rules and wear something I would wear if I was a guest at this wedding?
