Man Gets Real On Facebook About Women's Sizing After Trying On Girlfriend's 'XL' Clothing

"This bullshit right here is why we have 8 year olds with eating disorders."

It's a known fact that women's clothing sizes aren't exactly indicative of a woman's actual size.

A female could be a size six in one store, eight in another, and two in a third. And don't even get us started on vanity sizing...

And while we women are familiar with arbitrary clothing sizes, most men are not.

Case in point? Benjamin Ashton Cooper.

Cooper was helping his girlfriend clean out her closet when he noticed something that "didn't look right": a lot of her clothes were a size XL. Benjamin, who wears a size small or medium and sometimes even a youth large, decided to try on the clothes, and lo and behold, they fit. This really irked Ben, or as he put it "pisse[d] me off."

And while one commenter tried to correct Cooper, saying clothing sizes have actually gotten larger over the years, Ben was quick to clap back, pointing out his post was about "the disparity in sizing between men and women" and "body shaming sexism."

A guy who helps clean his girlfriend's closet and sparks a conversation about body shaming? Now that's relationship goals.
