What is the age requirement for a boudoir session? How old do you have to be for this amazing experience and when are you out of time? You must legally be 18 years old, although I really prefer working with 21 and older. To answer the latter, no age is too old. I have yet to photograph anyone in their 60s or older, but I'd love to do it! I bet you'd never guess this gem's age..and no, I won't give it away. A woman's age is only her secret to share.
