As I sit writing this at my desk in my trusty work-from-home comfies, I’m once again reminded just how functional and stylish a good pair of black leggings can be. No longer confined to the Pilates studio or sweaty halls of a gym, these timeless trousers have become a staple of the stylish dresser—which means I’m always on the hunt for a new pair. But today it seems my search is complete, after I spotted Sarah Pidgeon sporting a pair of flared leggings earlier this week.

Maintaining her signature Carolyn Bessette-Kennedy polish, the actress was spotted travelling through New York in an olive green fleece, black and white trainers, glossy leather bag and lime green wired headphones, but all I could see was her stylish spandex. Elevated with a subtle flare bottom, the 2000's athleisure staple is soaring in popularity right now, and although they might look like your run-of-the-mill pair, the brilliance of the flared style lies in its versatility.

Adding a playful yet polished finish to your look, the bootcut silhouette makes your outfit feel less rigid and more carefree. Easy enough to be styled with trainers but fitted enough to slide into knee-high boots, they've become an instant favourite with the comfy-casual crowd. And, by the looks of things, they’re set to pick up where your jeans pairs left off.
