Although neither Kim’s face nor North’s makes an appearance in the shot, fans get quite a good look as Kim’s most famous asset, which is barely covered by a white side-tie bikini.
“#TBT bye beach #PuntaMita #Mexico,” Kim captioned the cute pic.
The vacation, which the family took to celebrate Kanye West’s 37th birthday, was an action-packed adventure for the group, with Kim and North swimming with dolphins and North planting a kiss on a sea lion.
While it looks as though Kim and North thoroughly enjoyed themselves on their vacation to Mexico, it seems that some are less-than-pleased about the family’s trip south of the border.
Earlier this week, PETA SVP Lisa Lange slammed Kim’s decision to swim with dolphins during her trip, explaining, “Kim is free to leave the pool, but for the dolphins, it’s a lifetime sentence.”
