Jessica Portelli was shopping at a local clothing store when another customer made a body-shaming comment that she will never forget.
The 24-year-old U.K. resident heard the customer say that women like her "shouldn't wear a bikini."
"Initially, I thought it was some friend, pulling my leg … but I just told her I'll prove her wrong in two minutes," Portelli told The Times of Malta.
Portelli says she is size 18-20, and she hasn't always been as confident as she is now. But she wouldn't let that body-shaming shopper get her down. So she tried on a bikini in the dressing room and snapped a confident photo.
When she left the dressing room, she confronted the customer.
"I told her I was happy in my own body and that I love the way I look," she told The Daily Mail.
Portelli then shared her bikini photo on Facebook, along with an empowering message.
"You can be any size and look good," she wrote. "Confidence is what makes you sexy and not just being a size 6!"
The confidence paid off big time for Portelli. A worker in the store gave her a discount on the bikini for having to put up with the rude customer.
And after her response went viral on Facebook, she was happy that she was able to raise some awareness of her issue.
"The last few days have been crazy !!! I never expected to get all of this back just from one single post," she wrote on the platform.
