If there's one thing we can say about Jacquemus, is that the designer has models and Instagram girls wrapped around his finger – and with good reason.

Simon Porte Jacquemus has become synonymous with sexy, summer-friendly silhouettes inspired by the French Riviera, and has mastered the art of the luxury yet casual design approach. Another thing he's mastered is creating a trend. Remember the Le Chiquito bag? It was the catalyst of the tiny bag movement. The La Bomba hat? All of a sudden huge hats were everywhere! Now, we're looking at the Jacquemus logo cardigan.

They say three is a trend, and once we spotted this cardigan once, we knew there was more to come. Debuting as part of the La Montagne collection, the top is simple, yet sexy – in other words, classic Jacquemus. It features a dainty "Jacquemus" logo closure in gold hardware and comes in a handful of colors and designs, ranging from a long sleeve version to one in furry fabric.

It's already been worn by Kendall Jenner in the label's most recent campaign as well as on the runway, Megan Fox at an event, Bella Hadid off-duty, show-goers at Copenhagen Fashion Week, as well as by fashion's elite on social media. The top is Instagram gold – much like most things created by Simon Porte Jacquemus.

The various versions of the top are currently available to shop online, and you better be quick if you're looking to get your hands on one. You heard it here first, but this may just be the biggest trend item this fall.

If there's one thing that Jacquemus knows, it is how to make women feel sexy and elegant at the same time. I know, because I'm ordering a top as we speak.
