That's a big change, Kendall Jenner!
The 19-year-old reality star stepped out at a New York Fashion Week party on Wednesday wearing a see-through white dress and no bra that appears to reveal a recent nipple piercing.
The jewelry is even more apparent in this sheer top Kendall wore while walking the Diane Von Furstenberg runway on Sunday.
Kendall has taken her style in rebellious directions before. In June, the model ignored her sister Kim's advice about tattoos, and got a dot tatted on her middle finger.
You may practically need a magnifying glass to see it, but it's still a tattoo!
Meanwhile, as Kendall displays a new look for her boobs, her 18-year-old sister Kylie is denying rumors she had hers done.
"I'm gonna share with you guys one of my tricks," Kylie says in a video, explaining how she got her much fuller look. "I don't really share this with a lot of people, but everyone thinks I've gotten a breast augmentation recently. I haven't. I just use the Bombshell by Victoria's Secret."
"It's life-changing," she adds. "I've gotten all my sisters on it, all my friends, and if you ever want the look of bigger breasts, that's what I do."
