The Gone Girl star also posted a close-up photo of her tanned booty with a sandy handprint on it.
Ratajkowski isn’t shy about showing off her killer physique now, but did face lots of criticism as a teen model. In the August issue of Harper’s Bazaar, she opened up about the effects it had on her body image.
"Because of third-wave feminism, I understood that there are all these f**ked-up ideals of beauty put on young women; that there was something to be scared about in the entertainment world," explained Ratajkowski. "But yet the people I knew in my everyday life, they [didn't realize] their faux pas, their missteps, and since they knew me it was that much harder because the comments felt personal."
