Italian designer Giorgio Armani, the maestro of beige, injected bursts of blue, red and neon green into his Emporio Armani winter 2000 womenswear collection in Milan on Monday. Color was the main theme from the very first moment, when the designer sent out a group of models in black outfits highlighted with neon green detailing — a shoe, a glove or a shirt — which were greeted with applause from the surprised audience. The theme unfolded with a series of simple mix-and-match separates, each done in pure marine blue, black or white. Jackets looked like cropped, fitted sweaters. Skirts fell to the knee, and trousers were flat-fronted and low-waisted. Another rarity at an Armani show — high heels — made an appearance with slim, sexy skirts paired with sheer sweaters in pastel colors. For evening, bright blue, green or red-beaded halter tops — little more than a strip of color across the chest — were paired with color-coordinated trousers.
