Closing out the final day of New York Fashion Week was the trend-setting Ralph Lauren who featured several designs in 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.

There were also black-and-white checked pantsuits in the Charlie Chaplin-meets-Annie Hall mode with 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.
