They're a funny thing, trends. So fickle, so unpredictable. Take J.W. Anderson's Pre-Fall 2012 checked sweater, for example. Who could have known that it would be catapulted into must-have status in the space of just a few short weeks? With its oversize silhouette and graphic pattern, there's no denying it has appeal, but after being spotted — and photographed — on the likes of Taylor Tomasi Hill, Tamu McPherson, and Julia Sarr-Jamois at last month's Milan and Paris shows, this windowpane knit seems well on its way to replacing the striped shirt as the most ubiquitous patterned pullover around. In the slideshow, a few chic options.

In his 30-year career, Mario Testino has not only created some of the world's most provocative fashion images, but he's also photographed some of the world's most famous celebrities. Surprising then that, despite his status as one of the most well-known and prolific fashion photographers ever, there's never been even one US exhibit celebrating his work.

On Oct. 21, Boston's Museum of Fine Arts aims to remedy that with a major Testino retrospective. Titled In Your Face, the exhibit features over 125 of the legendary photographer's most iconic advertisements, editorials, portraits, and party candids, all of which were personally selected by Testino himself. And there's certainly no shortage of recognizable faces in the mix: Kate Moss, Jennifer Lopez, Madonna, Gisele Bündchen, Tom Brady, and more.

But if you can't make it to Boston before the exhibit closes on Feb. 3, 2013, never fear: Taschen has created a book by the same name to accompany the exhibit, and a selection of the images are available for your viewing pleasure right here.

Four of Hollywood's most intriguing ingénues — Scarlett Johansson, Keira Knightley, Mia Wasikowska, and Rooney Mara — were tapped to grace four special edition covers of W in honor of the magazine's 40th anniversary. Photographed by Steven Klein, each actress was styled in Fall 2012 pieces meant to represent one of the last four decades: Mara channels the '70s in patterned Prada and an oversize Albertus Swanepoel hat, Wasikowska is utterly '80s in snakeskin-printed Balenciaga, Johansson is the picture of glam '90s in black Dolce & Gabbana, and Knightley — almost unrecognizable with slicked-back blond hair — is a vision of the 2000s in sculpted Chanel.

Accompanying each cover is a Lynn Hirschberg-conducted profile that focuses on each actress's respective decade. "I think skinny jeans and micro-miniskirts are very unfriendly," Knightley says regarding her least-favorite naughts trend "I've been known to wear both, but on some days it seems like they were invented to make you feel bad about yourself." Meanwhile, Johansson has her own strong feelings about a certain '90s staple. "Men don’t like turtlenecks. I’ve never met a man who likes anything around his neck other than my hands."

All four covers hit newsstands Oct. 23. Preview them all here, in the slideshow.
