Olivier Theyskens

Olivier Theyskens delivered another minimalist-cool Theyskens' Theory Fall '13 lineup, and with it, came a fresh batch of ultratailored blazers, slouchy knitwear, menswear-inspired trousers, and slick leather accessories. It's a collection meant to be mixed and matched, layered up, and stripped down to its very core pieces — and with that kind of styling versatility, you know this is the stuff no-fail wardrobes are made of.

It's been said an ounce of prevention is worth a pound of cure, and some of the industry's biggest names seem to take that old adage to heart. More than one attendee of last night's opening dinner for the WWD CEO Summit told us that staying active is the best way to stave off sickness.

"I exercise a lot because I like to do Iron Man triathlons," Elettra Wiedemann said, "so I feel like my immune system is generally kind of boosted by all the exercise."

When we asked Theory CEO Andrew Rosen how he stays healthy, he said simply, "I go to the gym every day."

What other methods do fashion people use to stay healthy — or get well again — when cold and flu season strikes? The answers here in the gallery.

Most designers don't try to reinvent the wheel with their Pre-Fall collections, but Olivier Theyskens isn't most designers. So even though he said he "wanted everything to feel really essential" in his most recent Theyskens' Theory collection, that sentiment didn't stop him from being a little forward thinking.

Take for example, the multifunctional pieces here, like a jacket and miniskirt that combine to look like a belted coat, or a white poplin shirt long enough to be worn as a dress. (Theyskens instead showed the shirt tucked into a white A-line skirt.)

Elsewhere, fine-tuned basics dominated, like a slim-sleeve raglan sweatshirt, a dress made of denim, and several pairs of trousers cropped at the ankle. A subtle tartan added a flair to a trench coat and some shirts. Otherwise, the only print was one inspired by one of the essential things that holds New York City together: scaffolding.

Olivier Theyskens showed two kinds of women today at Theyskens' Theory's Spring show: the subversive working woman and girlie girl. Somehow, he made it work in his own genius way. Check out the collection in the slideshow and come back soon for our full review.

Olivier Theyskens's considerable talent for matching slouch with sleek was in full effect for Resort 2013. Among this season's standouts? A relaxed, cape-back jumpsuit with draped waist ties and a chiffon-sleeved minidress, the body of which was covered hem to hilt in sequins textured to shimmer like the skin of some exotic fish. While the details — a psychedelic oil-spill print here, a smattering of irridescent feathers there — lent a vaguely subversive spin, the palette of black, gray, and wine kept everything on the easy-wearing citified side. After all, "Resort is really about essentials that speak to modern life," the designer explained.
