COME SPRING, WHAT DO WOMEN want? Love? Work? Forget it. They want clothes. New clothes. Fun clothes. Unwrinkleable clothes. Washable clothes. Fresh spring clothes. You get the idea. Herewith, some of Washington's most sartorially savvy ladies tell what's the most important new item in their closet -- or on their mind -- this spring. HEATHER CASS, Cass and Associates, a Washington architectural firm: ''Something as architectural as possible. A pyramid dress by Issey Miyake. Influenced by the I.M. Pei pyramid in Paris. Either in white or black or both.'' ADRIENNE ARSHT FELDMAN, vice president of marketing, Susan Davis Companies: ''It would have to be something yellow -- a yellow-diamond yellow or a lemon-meringue-pie yellow. Yellow is like gold; I can't think of anything it doesn't go with.'' ANNA PEREZ, press secretary for Barbara Bush: ''An all-purpose lightweight-wool white dress with long sleeves and just over the knee. It must travel well and be on sale -- I have two kids!'' TIKI DAVIES, director of media relations, Kennedy Center: ''Something white and crisp and beautiful and laundered. Like a wonderful white dress that looks shaken out and starched. Something I'd wear for an outing on the Thames -- or, more realistically, for sitting under a tree at Dumbarton Oaks.'' NANCY DICKERSON, TV commentator: ''I like to look the same most of the time. I wear mostly Bill Blass clothes, and he's got a navy suit with white pique' collar and cuffs and a matching coat I love.'' MARY PETTUS, president of Mary Pettus and Associates Inc., a Washington public relations firm: ''A worsted silk suit by Hanae Mori, either a jacket with a full skirt -- at least midcalf -- or a pantsuit that would be loose but tailored. Clients prefer to see me in skirts. I'd wear the pants for evening. But either way, it would have to be a black-and-white combination.'' MARY LAYTON, director of the office of communications for the District government: ''A perfect pair of leather taupe pumps. Medium-size heel, open toe, closed back. I would just live in them. And anything but a narrow-cut Italian shoe!'' LESLIE DEVANEY, senior account executive, Mead Data Central: ''What I'm looking for is a honey-colored, sleeveless gabardine sheath. I'd wear it to the office with a blazer, at night with just sandals. It would be a tailored tunic to the knee, sort of like a Jackie Kennedy '60s dress.'' MAUREEN BUNYAN, news broadcaster, WUSA: ''A Valentino rose-pink hip-length jacket with a knee-length skirt in a lightweight wool. I like to look finished and professional on the air and in person.'' GEORGETTE MOSBACHER, chairman and chief executive officer of La Prairie Inc. and wife of Secretary of Commerce Robert Mosbacher: ''I'd love a pair of black patent-leather flats with rubber-tread soles for work. No ornaments, but maybe something like gold chains around the edges to camouflage the rubber.'' JOYCE TENNESON, artist-photographer: ''I always wear black. I'd choose something from Matsuda. A black pleated skirt to midcalf, and an asymmetrical jacket to the hips. Understated, but not conservative.'' DOLLY KAY, owner of Dolly Kay Design Ltd.: ''I got exactly what I wanted for spring -- a Jean Muir matte-jersey pajama outfit in apricot. It's got a suede jacket, short-sleeved blouse with turquoise sequins and palazzo pants. It doesn't wrinkle and is strictly for wearing at home or for traveling.'' ALMA ARRINGTON BROWN, public-affairs director, WKYS: ''A good pair of black linen pants. I like the new high waist, with pleats and fairly slim legs.'' ASTRA MICHAELS, investment officer, International Finance Corp.: ''I'd get a vest, one I could wear with or without a blouse underneath. I'd wear it with my collection of crosses. Not like the Madonna ones -- mine are Ethiopian and crusader styles that you wouldn't even know are crosses.'' MARTA ISTOMIN, artistic director of the Kennedy Center: ''A very classic -- like Chanel -- silk suit in a color such as royal blue. The jacket would be between the waist and hips. Straight lines and no minis.'' FRANKIE HEWITT, executive producer, Ford's Theatre: ''A smashing taupe- or wheat-colored three-piece suit in either raw silk or a very lightweight wool crepe. I like the look of Katharine Hepburn, you know, that classic ''forever'' look. The jacket would be loose and to the hips, with push-up sleeves. The skirt would have little pleats at the hips. I'd wear it with a silk or nice cotton white short-sleeved blouse that would be fluid, not crisp.'' WILHELMINA HOLLADAY, founder and president of the National Museum of Women in the Arts: ''The very best quality suit I could find. In heavy black silk with gold buttons. A jacket and below-the-knee skirt with soft, fluid lines.'' HELENE DE MARGERIE, wife of the French ambassador to the United States: ''I like Guy Laroche and Chanel. But since I never wear pants, I would have a suit, with a jacket and skirt. I like my knees to be covered. The jacket would be a quasi-white color -- I love white and navy for spring.'' CHRISTINA ORR-CAHALL, director of the Corcoran Museum of Art: ''A new dress for the annual Corcoran Ball. I like to wear dresses by D.C.-area designers, such as Vicky Tiel. Every spring I get to go out and buy one -- and my spouse can't complain!'' JOY ZINOMAN, founder, artistic director and managing director of the Studio Theatre: ''I'd like to go to Claire Dratch and let them show me things -- something dramatic, wild, funky. Maybe something in a tea-length gray satin, as befitting someone of advanced years!'' GLAUCIA BAENA SOARES, president of the American Film Festival: ''I very much like the dresses of Valentino. A linen dress in a dark blue or green, in a classic Chanel length. I've never worn a red dress; I feel awful in red.'' DIANA McLELLAN, Washington editor of Washingtonian magazine: ''A silk dress like a daffodil, both in shape and in color. Almost a costume, with a cape to midthigh that would have a mandarin neck and points like the back part of the flower. The dress underneath would be a trumpet dress with a low ''V'' in front; wide, curved shoulders; tight sleeves to the wrist; about four inches above the ankle. The bottom would be very frilly and slightly flared. There would be no mistaking what it was.'' LADY JENNIFER ACLAND, wife of the British ambassador to the United States: ''I just bought a very pretty bright-red Jaeger light wool crepe suit. I plan to wear it with a silk navy-blue-and-white spotted scarf. I love jolly spring colors.'' COLLEEN BENEVENTO, real estate broker: ''Something quietly elegant, like a two-piece navy Chanel suit. The jacket would fall a little below the waist and have a slight peplum, and the skirt would be to the middle of the knee.'' JAN PEDERSON, lawyer: ''I've bought a three-piece silk suit in tangerine by Genny. The double-breasted jacket is in linen, just over the hips, with long sleeves and gold buttons. The silk blouse has long sleeves and white buttons -- and the silk skirt is to the knee, all pleated, and has little white polka dots.'' ANNE E. ABRAMSON, publisher of Museum & Arts Washington magazine: ''I always look for something original. I'd even love a Jean-Paul Gaultier barbed-wire breastplate!'' BARBARA HARRISON, special-assignment reporter, WRC: ''Costume jewelry or a pair of big, fun, button-type silver earrings from Ylang-Ylang. Since people only see me from the waist up, my accessories should be interesting but not too wild or distracting.'' BERYL ANN (B.A.) BENTSEN, wife of Sen. Lloyd Bentsen: ''All my clothes are permanently square from being in suitcases! So although I don't wear a lot of jewelry, I'd choose a costume pin, the one accessory that can really change the whole look of an outfit.''
