Permission (2017)

Permission pertains to a few things: the permission to sleep with people outside of your relationship, for one. Perhaps more overarchingly, it's about the permission to do what you need to do to be happy. Rebecca Hall plays Anna, one half of a couple that's been together for 10 years - since high school. Her long-time boyfriend is Will (played by Dan Stevens), and after a drunken talk one night with her brother, the pair agrees to sleep with other people for the first time ever. Rebecca strips down to her bra after sex, shows sideboob in the shower, and plays the piano in a low-cut robe. We also see her topless during a post-sex scene with her beau!
