Kim Kardashian West is out to break the Internet once again. The 36-year-old reality star pulled out a vintage Dior bikini for a vacation in Mexico in honor of Kourtney Kardashian’s 38th birthday, and her body defies gravity in the tiny two-piece.

Kardashian West showed off her incredible post-baby weight loss in the vintage print bikini with a red, yellow, and green-striped band around the waist. She paired the skimpy two-piece with large gold hoop earrings, multiple chain necklaces, and Pucci reflective sunglasses.
