Retro, military and unisex style are the key looks to follow this fall

It's time to put away your swimming suits, shorts and flowing summer dresses and get ready for autumn outfits. Last March, fashion labels and couture houses alike presented their fall collections spotlighting three core styles. This autumn, aim for an androgynous look, military-inspired attire and a trip back to the 1970s and 80s.

Adopt the military trend, but the chic variety

As also seen in last year's collections, a number of fashion brands presented military-inspired pieces in the Fall/Winter 2015-2016 runways, highlighting military characteristics: khaki, wide-shouldered officer's vests and boots.

This year, discretion is key and designers have focused on the minor details and touches that evoke a military feel. Camouflage print is most definitely out and replaced by khaki garments mixed with other colors, stripes and uniform buttons. The result is much more feminine, sophisticated and accessible.

On the runway, khaki green was seen in a variety of shades and hues: designer Elie Saab presented a military vest with a stand-up collar and Isabel Marant used uniform-button detail to full advantage.

Back to the 1970s and 80s

Following the highly followed 1990s trend that has defined the past few months, the fall season takes us even further back in time to the 1970s and 80s -- a style loud with details of the era: turtlenecks (back in fashion since last year), flared pants, flower prints and vinyl.

The Loewe fashion brand paid particular attention to this era this season, showcasing extra-large and flowing pants, psychedelic prints and a lot of orange and electric blue. London by Topshop Unique and Bottega Veneta also presented wide-legged pants, in sync with the 70s and 80s vibe.

Androgynous vibe

Androgynous style was a staple of the fall collections this year with men sporting female attire and women showing off masculine wardrobes. Very much Cara Delevingne-inspired, the trend calls for three-piece suits and extra-large, boyish vests for winter, just as men are shown layering pants and skirts.

Vivienne Westwood went all out on this trend with a dose of punk allure, with models sashaying XXL vests with exaggerated shoulders and very masculine suits. Both John Galliano and Julien David also displayed several unisex looks, further boosting the trend for fall.
