Rosie Huntington-Whiteley Designed the Chicest Under-$50 Pajamas

Chalk it up to cold weather, shorter days, and the imminent holiday season, but this time of year, we always have a hankering to lounge around at home doing absolutely nothing. And what's necessary for such a self-indulgent endeavor? Chic pajamas, of course. Rosie Huntington-Whiteley clearly agrees with the sentiment, as she's included super-stylish loungewear pieces in her ongoing Rosie for Autograph collection at Marks & Spencer.

The model and actress Instagrammed a photo of one of her designs, revealing that it was her best-selling pajama set of the week. It's not hard to see why, either: For starters, the $49 price tag is easy on the wallet and makes it extra tempting to pull the trigger. Plus, the attractive floral print feels fresh and more seasonally appropriate when rendered in black. So what are you waiting for? These comfy-chic pj's are calling your name.
