I completely understand wanting to look your very best for this very important day, I love getting my makeup done too but my confidence in unfamiliar makeup artists on my small single eyelid asian eyes and "yellow" skin tone is low.
Actually, I'm an esthetician with a makeup background, a bit worried I will be nervous! But a couple of my BMs are in the industry too so I'm counting on them to make sure I don't draw my eyeliner all wavy.
With lots of practice, trial runs, the right tools I don't see why gals that want to do their own makeup can't. No one knows your face better than you and remember to blend, blend, blend.
Don't forget to take photos inside and out, close and far to make sure you get the results you want on camera!
