It's officially summer. After weeks of perfectly nice balmy weather, the nation is under a siege of sweltering heat. The 90-plus degree temps have spanned both coasts, leading some to call it a "heat wave." Basically, it's hot. Everywhere. But evidently, that doesn't seem to affect, distress or bother the A-list bunch so much.

Instead of typical hot-weather sartorial suspects, like shorts, flimsy tanks, and breezy dresses, certain celebrities are dressing for fall—and even winter. They're either living in an air-conditioned bubble invisible to the naked eye, or they're somehow magically immune to the heat. (Meanwhile, we—aka normal folk—are doing everything we can to battle and answer every sweat-related problem we have.) After a brutally cold winter in which stars forgot it was, well, winter, they've gone and done a complete 180. From heavy-knit sweater dresses to leather culottes, here are eight times celebrities forgot it was summer from the past few weeks.

It's an edgy look for Holmes—one that we happily welcome. But, we were a tad distracted by the long-sleeve metallic sweater and her pleated leather Zac Zac Posen culottes.

The central keyhole detail and the dangerously high slit may serve as summery ventilation, but the high-neck long-sleeve top and the rich burgundy hue scream fall to us.
