They’re in Mykonos, Greece, celebrating their elder sister, Alana Hadid’s 34th birthday.

And the trip continued for Bella, 22, and Gigi Hadid, 24, on Monday, with the models stripping down to their barely there ʙικιɴιs for a day in the sun.

While the younger model dressed in a simple brown triangle ʙικιɴι design, Gigi couldn’t help but show off her wild side in and animal print two-piece.

With both sisters clad in ʙικιɴιs, all eyes were on their extremely long and lean legs and washboard stomachs.

Bella accessorised her beach look with two gold pendant necklaces and a delicate gold chain resting elegantly around her hips.

The Vogue model styled her brunette tresses into two braids with statement hair clips, and appeared to be makeup free for the day in the sun.
