Along with Balenciaga, Versace and Hussein Chalayan, Stella McCartney led fashion's sci-fi trend this spring. At the meatpacking-district store, I found this short silver dress. The silk-polyester material felt so light, I wondered for a moment if it was a high-tech fabric, and the straight fit was flattering. But the gigantic, elastic-cuffed sleeves looked like metallic trash bags. My childhood heroine, Anne of Green Gables, may have loved puffed sleeves, but I don't want to go back to the future. 429 14th St., nr. Ninth Ave.; 212-255-1556.
