STORY: Mercedes-Benz Fashion Week in New York drew to a close on Thursday (September 12) with prim, 1960s-inspired looks from Ralph Lauren.

Among the last of the hundreds of fashion shows that filled the week, the trend-setting Lauren went relentlessly black and white - a theme among many designers this week - then switched to eye-popping fluorescents.

His black wool crepe ottoman jacket worn over a knitted vest, white cotton shirt and black tie, along with black silk shorts and patent leather Mary Jane shoes brought to mind a tomboyish schoolgirl.

Black-and-white checked pantsuits in the Charlie Chaplin-meets-Annie Hall mode featured oversized lapels.

The youthful looks were accessorized with newsboy caps or Harry Potter-style spectacles.

Balancing out the collection were blocks of unearthly fluorescents, including searing neon leather jackets topping miniskirts.

The fashion world's attention now turns to spring and summer 2014 collection shows in London, Paris and Milan.
