Kylie Stole Her Mom's Bathing Suit For Mexico

After a week of swanky dinners, blowout parties, and $400,000's worth of presents, Kylie Jenner is still celebrating her 18th birthday. Moving the party down to Mexico, Kylie packed Kris Jenner's bathing suit and more amazing beach ensembles to prance around in alongside her squad of famous gal pals. Talk about major FOMO. Seriously, what does it take to get inducted into that crew?

Among the fashionable gang are Kylie's BFF Pia Mia, her sister Kendall (obviously), and their mutual bestie Hailey Baldwin. Each starlet was dressed to the nines, decked out in some of the sultriest bikinis I have ever seen — all of which I'd like to add to my own collection, thank you very much.

The youngest Jenner sported multiple wow-worthy suits (naturally) in varying types of colors and cuts. She started off with a purple two-piece that featured a strapless top and a matching cheeky bottom. She then debuted a hot pink onesie that read "Body Glove" across the chest, which emulated the look of an old-school Baywatch babe. Almost literally, in fact; it was her mom's in the '80s. Her third style was a skimpy white bikini with a cropped halter top and a high-rise bottom — my personal favorite so far. I have no doubt that the 18-year-old will continue stunning in sexy swimwear, so I'll be keeping an eye on her.

Meanwhile, Kendall flaunted her supermodel assets in a white crochet bikini that combined laid-back vibes with a touch of glamour.

Let's take a look at all the incredible swimwear from the trip, along with similar alternatives to recreate the sexy styles at home.

Kylie Jenner

This retro-looking piece is giving me major '80s nostalgia.

Missguided Beach Vibes Swimsuit, $45, asos.com

This coral one-piece comes pretty damn close to Kylie's/Kris' hot pink version.

This stunning violet two-piece is sporty, yet sexy at the same time.

Winnie New York, $89, triangl.com

This bandeau neoprene number has a very similar style to Kylie's purple suit.

This is by far my favorite of the three looks.

Morocco Bikini Top, $115, revolveclothing.com; Sunset Bikini Bottom, $75, revolveclothing.com

This two-piece is a bit more intricate than the one Kylie sported, but still incorporates the cutouts and strings.

Kendall Jenner

I love all things crochet.

Daisy Chain Crop Bikini Top, $103, revolveclothing.com; Daisy Chain Cheeky Bikini Bottom, $110, revolveclothing.com

Is this not a spitting image of Kendall's bikini?!

Pia Mia

This super vampy lace number is one of my favorites.

Gunpowder & Lace Triangle Top & Skimpy Bottom, $260, beachbunnyswimwear.com

Obsessed.

Hailey Baldwin

Hailey's pale grey suit has vintage vibes, and I'm totally digging it.

River Island Cami Bikini Top, $27, asos.com; River Island Cami Strappy Bikini Bottom, $22, asos.com

This printed suit is similar in style to Hailey's, and definitely make you stand out at the beach. Time for an end of the summer vacation, I'd say.
