Florence attended a Valentino runway show in Rome on 8th July, and she opted to wear a hot pink gown from the luxury fashion label with a see-through bodice
In an Instagram post shared on 10th July, the 26-year-old star revealed that she had been bombarded with negative messages about the dress and her body.
According to Pugh, while she expected "commentary" on her choice of outfit, it was interesting to witness just how easy it is for "men to totally destroy a woman's body, publicly, proudly."
"It isn't the first time and certainly won't be the last time a woman will hear what's wrong with her body by a crowd of strangers, what's worrying is just how vulgar some of you men can be," she wrote.
"So many of you wanted to aggressively let me know how disappointed you were by my 'tiny tits', or how I should be embarrassed by being so 'flat chested,'" she wrote
She then advised those who left derogatory comments on her post to "Grow up. Respect people. Respect bodies. Respect all women. Respect humans."
Pugh signed off the post by alluding to Instagram's ban on photos of female nipples, adding the hashtag "#f**kingfreethef**kingnipple."
Pugh's post was hailed by fans and fellow celebrities, who left messages of support
