Lady-like with fizz – just like good champagne. That’s Oscar de la Renta’s forte. When his models hit the runway to preview Spring 2005, he marked his 40th year of dressing America’s doyennes of fashion including film stars, first ladies and three generations of socialites. This season he leads the crisp black and white line-up for casual looks and flowering colors for evening. His talent for mixing fabrics and flattering all ages is as legendary as his Latin charm with women.
