Kim Kardashian Flaunts Her Bikini Bod in Yet Another Selfie from Her Mexican Vacation

Kim Kardashian Wests Mexican vacation is the gift that keeps on giving.

The 36-year-old reality star is on an extended tropical trip with sister Kourtney Kardashian and a handful of their closest gal pals, in celebration of Kourtney’s birthday. And while the getaway had been filled with sun-soaked boat rides and late night parties, it appears the real perk of the getaway has been the opportunity it’s provided Kim to show off her endless collection of bum-baring bikinis.

Case in point: her latest Instagram shot, posted in the early hours of Friday.

Filtered with Kim’s signature vintage-inspired VSCO HB2 grain, the photo shows Kim casually looking off-camera, her hair braided back, while wearing a white thong bikini its top covered by a cut-off and tied white T-shirt. She gave the photo a simple caption: “Hey.”

On the off chance one has missed every single tweet, Snapchat, Instagram story, and selfie produced by the Keeping Up with the Kardashian klique this week, Kim’s look on Friday appears to be an outfit she rocked on Snapchat earlier in the week - proving she’s either reached the stage where she’s run out of new skimpy swimwear items to debut (gasp) or she’s actually just sneaking in a flashback Friday post without using the proper hashtagging (tsk tsk).

Either way, Kim has surely racked up enough flesh-baring, swim-ready shots to fill a whole calendar by now - though Kourtney is hot on her tail.

The eldest Kardashian sister, 38, had her collection of barely-there two-pieces on ready - doing cartwheels across the lawn of their rental property in a black Fox Swim top that tied in the back and thong bottoms one day, and rocking a similar navy blue velvet version from Triangl while catching rays on a boat the day prior.

Kourtney may be looking good, but she hasn’t alway felt good.

On Monday, she told fans in a tweet that she’s partied a little too hard writing, “I may or may not have thrown up four times last night and slept in #birthdayvibes.”

Kim was more than happy to share some of their raunchy adventures on her Twitter account, giving fans an in-depth account of what really went on. Nipple clamps, sex toys and naked cartwheels seemed to make up the bulk of the evening. What happens in Mexico, apparently, does not stay in Mexico.
