One fitness influencer wants you to know that social media is all about illusions—no ifs, ands, or butts.

Sia Cooper, who runs the popular Instagram account @diaryofafitmommyofficial, often shares side-by-side images of her body to denounce unrealistic beauty standards and point out how different angles can influence what a person looks like on camera.

Last week, she posted brilliant insight into butt selfies—showing her followers how pulling up your underwear a certain way can totally change the look of your booty.

“PSA: UNDERWEAR PLACEMENT MATTERS,” Cooper captioned a set of mirror selfies. “If you hike your undies up really high, it’ll give an illusion of a tinker waist and bigger bum. Just another popular trick amongst Instagram fitness models! So don’t be fooled.”

This side-by-side was not a suggestion that her followers lift their undies up next time they take a belfie. In an honest disclosure, she provided an all-too-relatable postscript: “Having a 24/7 wedgie is not fun under any circumstances.”

Commenters praised Cooper for her transparency and thanked her for a much-needed reminder about the almost too-perfect body parts you see on your feed. A couple of days later, she illustrated her point by posting a photo of her “real booty” and then her “IG booty” with repositioned underwear.

“It’s amazing what a little bending forward, hiking up your underwear, arching your back, and sticking your booty out can do,” she wrote. “A picture is just a split second. We all look different from different angles.”
