Good thing she packed a lot of bikinis! Kendall Jenner, 17, has been thoroughly documenting her family vacation in Mykonos, Greece this week by sharing several photos on Instagram of her wearing tiny bikinis.

In one photo collage, Kris and Bruce Jenner's second youngest daughter models a strapless bikini, offering front and side views that show off her thin frame. "Mellow moods got me, darlin'," she captioned the filtered shot on Saturday, Apr. 27.

In another collage she created, Jenner shows of scenic pics from their trip to "paradise" as well as a close-up shot of her ultra-slim waist. "This place is just too beautiful," she wrote on Apr. 30. "Good times."

Jenner has recently gone on the defense over criticism that she's too thin. "I'm constantly criticized for being too skinny," she told the April issue of Harper's Bazaar. "I'm trying to gain weight but my body won't let it happen. What people don't understand is that calling someone too skinny is the same as calling someone too fat. It's not a nice feeling."

In addition to enjoying the beach and beautiful scenery, Jenner has been indulging in the cuisine. On Apr. 30, Jenner tweeted a picture of her dessert with the caption, "Yummy apple pie with ice cream!"
