The pictures flashed from the White House dinner honoring Prime Minister Lee Kuan Yew of Singapore and Mrs. Lee last week showcased the bare dresses of Raquel Welch, Brigitte Nielsen and Natalie Cole, but one of the most handsomely attired was designer Donna Karan, who was wearing the black cashmere bodysuit and gold-sequined scarf skirt from her madly successful first collection.

Karan, who was seated at the table with Nancy Reagan, Prime Minister Lee and Sylvester Stallone, says that in spite of her nervousness, she found the perfect accent for her upcoming spring collection. With all the navy blue she'll be showing, she's planning to borrow some of the details of the crisp uniforms of the Marine Band. "In fact, a few marines might just help the show a lot," she laughs.

She also took close note of the way other guests looked. "Mrs. Reagan looked gorgeous, so gentle, so elegant, so appropriate." Mrs. Reagan told Karan she was a great fan of the designer's clothing. And like all designers, Karan would love to see Mrs. Reagan in her clothes. But she admits, "She has the build for my clothes. However, her own taste and the way she presents herself are perfect; I wouldn't encourage her to change a thing."

About her own dress for the evening, Karan says she felt "very comfortable." She added, "Thank God the skirt had big pockets. I had to take home the napkins, the matches, the menu and the flags to remind myself it really happened."
