It seems like you're referring to two different movies: The Bow and The Devil Wears Prada.
The Devil Wears Prada (2006) is a comedy-drama film based on the novel of the same name by Lauren Weisberger. It stars Anne Hathaway as Andy Sachs, a young journalist, and Meryl Streep as Miranda Priestly, the demanding editor-in-chief of a fashion magazine.
The Bow (2007), also known as Bow or La Moue, is a French film directed by Julia Ducournau. It's a short film, but it has received some attention for its unique and disturbing scenes.
