Kylie Jenner is no longer a teenager! As of today, the Lip Kit mogul is 20 years old and is celebrating her birthday with a *very* grown-up swimwear look.

The reality starlet took to Instagram to post poolside pics of herself wearing what might have been the nude-est bikini we鈥檝e seen on her yet.

The flesh-tone hue of the suit, paired with its itty-bitty string-tie sides, was hardly visible at all in certain lighting (or lack thereof). 鈥淒ay at mommy鈥檚,鈥 she captioned the first snap, with a sole sun emoji captioning the second.

While her look wasn鈥檛 quite as barely there as big sis Kim Kardashian West鈥檚 vintage see-through Helmet Lang dress, it was still enough to have us doing a MAJOR double take. And with close to three million likes on both snaps in a single day, we鈥檙e clearly not alone.

It certainly seems like the youngest Jenner definitely has a preferred swimwear *lewk.* She wore a similarly colored bikini back in June of last year (while sporting those questionable cornrows).

She also tried the neutral shade out in a one-piece with a 鈥淧leasure鈥 script around the same time. What can we say? She loves the flesh-toned suits! We wonder if she and Bella Hadid ever swap closets?

What do you think of Kylie鈥檚 naked suit? Tell us over @BritandCo.
