I think there was no braces scenes in 'Brady Bunch Movie', maybe you mean the movie 'Very Brady Sequel, A'

Please never use the 'code' for example iFemale in regular posts. I use the Code to mark only the movies in database. When you want help us, describe the Braces scene exactly. When you have a new movie, I will addet this title to database, as soon, as possible.

Example:

Teenage daughter Jan (Jennifer Elise Cox) has braces - many good shots throughout the movie. In a couple of scences she also wears a high-pull headgear. Later in the movie she meets a handsome teenage boy with braces.

So long, Marty
