The designer's spring 2015 collection was heavy on khakis, safari jackets and cargo pants, and played with the notion of safari as it moved from casual daywear into evening looks, too.
Lauren described the collection as "about an exotic kind of luxury, the spirit of a romantic safari emboldened by luminous colours played against the heritage of pure khakis in sleek and modern shapes. "
His final item was the starkest example: a sage green silk taffeta evening dress that looked like a casual safari jacket on top, only with a skirt billowing out like an evening gown on the bottom.
The runway show, at Lauren's downtown showroom, began with casual cargo pants, dressed up with an amethyst silk top, or a billowing bright yellow blouson jacket. The safari luxury theme continued with a coat and skirts in sage green metallic organza, a shimmering fabric that looked almost like camouflage as the models whisked by.
Though the colour scheme favoured safari hues like sage green and tan, there were bright bursts of colour, too, like a safari shirt dress in a brilliant poppy red. There were shiny beaded tops, too, lending a whole lot of bling to otherwise understated outfits. A poppy tulle evening dress was followed by one in equally bright lemon citrine.
In the front row at Lauren's show, which always comes on the final day of Fashion Week, was actress Julianne Moore.
"When I first moved to New York City, the Ralph Lauren store on Madison Avenue was the first one I went to," the actress recalled. "I used to wander around and wish I could afford the things that were there!"
