Paris Fashion Week is in full swing and, apparently, it's unseasonably hot. Like, in the eighties and glaring-sun hot. We've heard reports of editors freaking out about bringing the wrong clothes, and supposedly Net-a-Porter is even running a special express delivery service to hotels for editors who didn't pack for the heat wave. But we're seeing many a brave fashion soul defying the temperatures, most brazenly by wearing leather. Marie Claire's Taylor Tomasi Hill stepped out in a sheath dress made from the material, while Town and Country's ​Sophie Pera went for Jim Morrison–esque skinny trousers. Anna Dello Russo and​ Averyl Oates, the buying director at Harvey Nichols, also opted to sweat it out. However, lightweight leather was a big trend on last spring's runways, so these ensembles are actually pretty well-suited for the Indian summer. See these looks, and more — like a photo of Cecilia Dean looking more unabashedly girlish than we ever have, in a blue floral frock — in the slideshow ahead.
