We're finally getting into the warmer weather months, and while in the process of of storing our sweaters and salt-covered boots, we can't help but think back to some of September's runway trends for some new wardrobe inspiration.

When it comes to skirts and dresses this season, you can bet we're coveting the pleat that showed up at Oscar de la Renta, Michael Kors, and many more.

Click through the gallery to see the full evolution of the trend -- from the runways and red carpet, to the bloggers, and the pieces you can shop right now.
