The 18-year-old is known for taking risks with her fashion and recently has been channelling big sister Kim Kardashian West with plenty of crop tops, figure hugging dresses and high waisted pencil skirts.
But for an appearance on America's Today show on Friday (12 February), she proved she's a total style chameleon by opting for a pretty white lace babydoll dress instead.
How much does she suit this look?!
Kylie was on the show with sister Kendall, 20, to talk about their new clothing line, Kendall & Kylie, so naturally the cute frock is a little number from their own line. It's also available in black.
Model Kendall also supported their own line (obviously!) by choosing a black cropped top and wide legged trousers from the collection.
Speaking on the show, Kendall said: "I think it's something our fans have always wanted. They're always looking at our style and trying to copy it. We wanted this to be our mature line."
Kylie added: "I like to ask my fans for advice on Twitter or my app."
