As part of the never-ending amazing collaborations Opening Ceremony features, Chloë Sevigny has partnered with the Robert Mapplethorpe Foundation to release a series of t-shirts featuring the work of the late photographer. Beyond the standard t-shirt cut, some of the photographs and collages are printed on cropped tees, with a portion of the proceeds going to the foundation. The line will be available for pre-sale, online only, this Monday, December 13.

Recognized for carrying edgy designers both new and known, Oak NYC is a mandatory stop for local style mavens and in-the-know out-of-towners. Last year Oak launched an in-house line, A.OK, offering the same unique luxe but with a lower price point (most items are under $100). Their e-boutique draws the same appeal, stocking coveted designs from the likes of Commes Des Garcons, Damir Doma, and Rad Hourani.

My favorite thing about a fully buttoned shirt is how it can instantly make any outfit look super-polished. Worn with everything from prep skirts to vintage cut-offs, a white button-down oxford is something everyone should have and probably already does (think of your trusty interview outfit you haven't touched in ages). I love the fitted version Hanneli Mustaparta snapped of the girl above, as well as a more loose style in billowy silk or chiffon. These shirts look just as good styled in a more relaxed way, but there's something about that top button and a well-displayed collar that changes the whole vibe.

Already, London Fashion Week is well under way, and one of the most anticipated runway shows -- Topshop Unique -- has wrapped. Rather than go against the fashion grain, Topshop's namesake line tends to fall smack dab in the middle of the latest fads, neither pushing the envelope or falling behind it. And consumers are just fine with that. So, what's the latest on Topshop Unique's 70s-themed menu for spring? Set to a soundtrack that included Stevie Nicks, the show included mannequins with wildly untamed frizzy 'dos and accordingly eclectic ensembles. Floral and suede trousers (worn loose, as seen at NYFW) were paired with psychedelic silks. Sheer was applied to tops as well as to ethereal maxi dresses. Graphic prints were splashed across rompers and flowing jumpsuits for a collection that, overall, screamed rock 'n roll Gypsy.

With boys dressing like girls and girls dressing like boys, there's no stopping androgyny this fall. Out are the sexed up short skirts and sky-high stilettos of last fall, in are unisex and gender-bending silhouettes, including tranny-friendly styles. Not only did Givenchy's Ricardo Tisci cast a transgender muse as lead model for the brand's FW10 campaign, Acne has now teamed with Candy (fashion's first transgender and transsexual-themed magazine) to create a line of tailored shirts specifically for cross-dressers. "The Swedish label and the publication's editor, Luis Venegas, have together designed a capsule collection of three androgynous shirts, made in both silk crepe and Italian denim. The styles are available in two washes - stonewashed and bleached," says Vogue UK of the shirts, which are named after Dynasty stars. Choose from Alexis, Sammy Jo, and Krystle.

Hats have been staging a return to the sartorial spotlight ever since Miuccia Prada brought back the turban a few seasons ago. Tavi made waves when she sported a larger-than-life chapeau courtesy of Stephen Jones at a recent fashion week presentation. So too have bow headbands, bunny ears, and straw boaters been crowning famous heads. Come fall, headgear is due to start widening its reach and expanding to even grander proportions. Caps are getting wide.

Men's Spring/Summer 2011 shows have just come to a close in Paris, and the biggest takeaway from France and Milan seems to be an unexpected, sweeping push toward gender-bending by way of crop-tops, jeggings, and other decidedly effeminate styles. But androgyny isn't the only newcomer to menswear this season. Meet the next big shade, Acne's reflective sunglasses. From Alexa Chung-approved wedges to a coveted bi-annual print publication, Stockholm-based Acne has been sailing into uncharted sartorial waters since its initial launch as denim label, so it's no surprise that they're leading the way in eyewear, too. Good bye, Wayfarers.

Don't put either Diane Von Furstenberg or Acne--the Swedish fashion brand and design collective--in a box. In fact, both are expanding this season in a rather unlikely way: furniture. Neither method of branching out is necessarily a surprise. Acne, for starters, is no one-trick pony: its collective is responsible for a coveted bi-annual magazine, and equally drool-inducing fashions and advertising. Besides, its head, Jonny Johansson, actually got his start designing furniture. Johansson has remained relatively mum about details, although he has cited mid-century, Swedish master Carl Malmsten as his inspiration. "The hand-crafted nature of [his] pieces sums up the handy crafting movement and it’s simplicity and quality is super interesting to me," he told Grazia.

When it comes to multitasking, few brands do it better than Acne. The Swedish fashion brand-cum-magazine-cum-creative collective has managed to stay ahead of the curve for many seasons, putting forth ensembles as interest-piquing as the interviews in their oversized bi-annual publication, Acne Paper. Hint Magazine recently spoke with Jonny Johansson mid-vacation (and mid-Metallica kick) with his family in Stockholm. Right off the bat, Johansson explains how the recession has actually been good for business.
