"Yacht Life," Simpson wrote, hashtagging the image #FBF (Flashback Friday).
Just last week, Kylie shared a selfie of her wearing the same cleavage-baring suit.
But it was the 17-year-old's older sister that was first spotted modeling the popular swimwear, which retails for $450.

"Me and my lil monkey inside my @Allure_Magazine cover shoot," Kendall, 19, captioned the photo taken by Mario Testino.
Simpson and the Jenner sisters aren't the only stars posing in this sexy swimsuit. Model Abbey Clancy also put her curves on display in the monokini.
It seems this slashed style is a win for lots of body types.

While Kendall and Kylie do seem to be leading this swimsuit trend, they revealed to ET where they get their own fashion inspiration from. "I think we get it a lot from our sisters," Kendall said of their older siblings, Kim, Kourtney and Khloe Kardashian. "Growing up around them and they are pretty stylish... we learn from them."
Who do you think wore the swimsuit best?
