Ever watched the show Look-A-Like? Now in its sixth season, the premise of the show is that a team of experts—a hairstylist, makeup artist, stylist and photographer—transform regular civilians into their celebrity doppelgangers. Fun, right? I got to visit the set and on that particular day of filming, the team was working on a Katy Perry transformation. WOW. Makeup artist Paul Venoit was able to share some great tips on how to do classic, retro, pin-up girl makeup.
