In the episode ‘Hot Child in the City’ Miranda (Cynthia Nixon) is prescribed braces to cure her headaches which make her feel like an uncool teenager again. Worse: the braces she has are apparently old-fashioned; eating caviar is so embarassing; and, worst of all, they cramp her lovelife when her lover gets entangled.
Incidently, this was not the first time Cynthia wore fake braces on screen – her character had braces in Let it Ride. She also wore dentures when playing Eleanor Roosevelt in Warm Springs.
Judy Chin was key makeup artist and Kerrie R Plant was makeup artist (Cynthia Nixon), but I don’t know who was responsible for Cynthia’s braces; if anyone can confirm the credits, please email theMAKEUPgallery.
