After concluding some of the most insane 18th birthday celebrations the world has ever seen (including a Ferrari, Birkin bag and a cake in the shape of her lips), Kylie Jenner and a flock of her friends flew down to Acapulco, Mexico to 鈥 what else? 鈥 continue celebrating. With a new line of shoes and news-making hair color that changes like the tides she鈥檚 splashing in, Kylie is far from a normal teenager. Her latest antic, which Kris Jenner just called her out on, however, is something to which we can totally relate: 鈥渂orrowing鈥 from her mom鈥檚 closet.

Mama Jenner posted this incriminating photo on her Instagram today along with the caption: 鈥淥hhhhhhh so THIS is where my vintage Body Glove bathing suit went!!!! @kyliejenner you are grounded! Wait, I can鈥檛 do that anymore you鈥檙e 18鈥.#whoworeitbetter #80鈥檚 #whoknewyouwouldlikemyoldstuff #recycle #love #mexico #acapulco1989鈥

Clearly, mom鈥檚 not really that mad. Plus, the retro, Baywatch-esque one piece is having a moment, so good for Kylie for giving that vintage swimsuit some time in the sun. Here are five hot, hot pink styles to help you cop Kylie鈥檚 (and 鈥80s Kris Jenner鈥檚) sizzling style.

1. Prism Los Angeles Swimsuit ($166): This head-turning bathing suit from Prism is anything but boring. With a scoop neckline for that va-va-voom and cable-knit strips, it鈥檚 definitely a piece your kid will be stealing from your closet in twenty years.

3. J. Crew Neon Scoopback One-Piece Swimsuit ($70): This sultry swimsuit has a super low back, so you can still show some skin. It also some in regular and long-torso sizes, so tall girls can enjoy the fuchsia too.

4. Indah Pagoda Crochet Swimsuit ($193): This splurge is totally worth it. This eye-catching Indah one-piece is reversible, has an on-trend racerback style and features intricate crochet details along the side.

5. Tory Burch Solid Logo One-Piece Swimsuit ($137): This hot pink number by Tory Burch will definitely stand the test of time. The super low V-neck + pretty gold logo combo is the perfect mix of sugar and spice.
