This season, it's all about sleeves

Fashion's got something fresh and new up its sleeve this spring - or more precisely on its sleeve.

In fact, it's all about the sleeve as big brands and high-end designers are lavishing sleeves with their undivided attention. The variety is vast, ranging from wildly exaggerated bells to voluminous balloons to more moderate flares and puffs along with fluttery ties and ruffle details.

"We're calling it the power sleeve," says Adam Glassman, creative director of O, The Oprah Magazine, who likes the style so much he dressed his boss, Oprah Winfrey, in a variation on the theme for April's cover.
