"Modern Family" star Ariel Winter took to Instagram to slam slut-shamers following a wave of people criticizing her for posting a bikini photo while vacationing with family.

"Who knew that an innocent photo with my nieces would turn into this? The height of a girl's skirt or whatever she is wearing for that matter, does not imply what she is asking for," the post read.

The 17-year-old said it sickens her to think that a simple photo she posted with her little nieces meant that she was "asking for it."

"I typically never give power to the mean things people bravely say behind their computer screens on the Internet, but this is for the girls who are constantly bullied whether it be online or at school," the post continued.

"You are not asking for anything because of what you are wearing- you are expressing yourself and don't you ever think you deserve the negativity as the consequence to what you are wearing- YOU ARE BEAUTIFUL. Celebrate you and don't let anyone's comments allow you to think less of yourself. Us girls have to stick together!!!!!!"

Meanwhile, Winter showed off her new breast reduction surgery last month when she attended a family wedding with her longtime boyfriend Laurent Claude Gaudette.

Winter, who plays the role of daughter Alex Dunphy in ABC's "Modern Family," went under surgery back in June to reduce her breasts from a size 32F to a size 34D.

The actress said the procedure was worth it because she was suffering from back pain. She also noted after her surgery, other girls are inspired to do the same thing.

"Girls are tweeting me and saying like, 'Oh, this wouldn't be accepted where I am, but now that you did it and opened a conversation about it, I can actually like talk to my friends and family about the possibility of this,'" she said.
