Many fans were moved by Khloe's request that commenters don't "ruin" how she felt about the look. The Keeping Up With the Kardashians star has been candid in the past about how criticisms over her looks have affected her through the years.
Back in April, she opened up after an unapproved bikini photo was released of her online.
"You never quite get used to being judged and pulled apart and told how unattractive one is," she wrote. "But I will say, if you hear anything enough then you start to believe it."
