If you spent the summer months swanning around in the season's favourite knee-length pencil skirts, then you've come to the right place. Picking up where the knee-grazing trend left off, fashion people are making a hard turn towards the maxi pencil skirt trend this autumn.

Establishing it as one of the season's new favourites, I spotted Lily Allen taking the trend for a spin just this week. She opted for a deep grey style that neatly skimmed her frame without clinging to it—as, in my opinion, the chicest pencil skirts always do. Extending well beyond the knees and cutting neatly at the ankles, the skirt created a sleek, polished silhouette. Styled with a semi-sheer blouse, Lily's look was largely covered up, but the blouse's form-skimming shape and transparent finish brought an understated sense of sexiness that made her maxi-skirt outfit feel even more evening-ready.

Casting a '90s-inspired silhouette without feeling at all dated, long-line pencil skirts retain the simplicity and fuss-free energy that made their shorter counterparts so appealing in the first place. And, much like the knee-length styles we've been wearing all summer, they work effortlessly with the wardrobe basics already in your rotation. From simple shirts—as Lily so elegantly demonstrated—to go-to T-shirts and strappy tank tops, they bring a polished, pulled-together energy to any outfit.

So, if you lived in knee-length skirts this summer, consider these your autumn upgrade. Read on to shop my edit of the best Lily-worthy pencil skirts to add to your rotation now.
