One patient told The Mimi Foundation that the thing she missed most about life before cancer was being carefree.
So the French charity paired up with Leo Burnett France and offered 20 patients make-overs.
The only condition? They had to keep their eyes shut and allow a photographer to capture their reactions.
What these women didn't know is quite how silly their make-overs would be.
The idea was that as soon as they saw how ridiculous they looked, they'd laugh and remember what it felt like to be carefree.
