Costello Tagliapietra: Jeffrey Costello and Robert Tagliapietra's fall collection had the crucial three S's that have become their mainstay — slim, sexy and sophisticated — and that, in itself, was a testament to their confidence. With zero adornment but for a few luxurious CT for Saga Furs, they let the clothes and their impeccable tailoring do the talking. The designers stuck to their choice fabric for fall, wool jersey, in a palette of browns, cool blues and greens that complemented the mostly mock or cowl necklines, bare backs and knee-skimming skirts. What was new this time around were the cool velvet shawl-collar coats and the pleated straight-leg trousers. Add a gown or two and the hard-to-please modern woman's got herself a wardrobe.
