Naeem Khan keeps the glamorous gowns but adds daywear and casual separates - and flat sandals

NEW YORK, N.Y. - The models must have been grateful — especially their feet.

At Naeem Khan's Spring/Summer 2013 preview on Tuesday, most designs, except the fanciest gowns, were paired not with the usual stiletto heels but with flat sandals, like ones you'd saunter over to the beach in.

The Indian-born Khan, who famously designed Michelle Obama's first state-dinner dress, a shimmery gold-and-silver creation, remained true to his glamorous roots, presenting a number of red-carpet-ready gowns.

But he also broadened his collection by adding separates and daywear, as in cotton sateen pants paired with a bustier, or a cashmere off-the-shoulder sweater, or a quilted trench in bright blue.

Often, Khan would present a motif, like a black-and-white rose print, and move from casual to fancy, as in a plain shift dress or a trench coat to a cocktail dress to a trumpet gown.

A hit was a sepia sunflower print slip dress, simple and dramatic at the same time.

The crowd at Lincoln Center also seemed to like his blue multi-wave print, which looked a little like an Impressionist painting; he presented it in a sheath dress, a shift and, most successfully, in a strapless cocktail dress.

On the colour palette, Khan went from black-and-white or sepia prints to a brilliant marigold, coral, bright blue and orange.

Khan ended his show with a series of beaded chiffon caftans, in marigold, coral, blue and blush.
