‘Hello Cliff?This is Donna.” Donna Mills, that is. “She wanted to know what to wear with an outfit I designed,” reports Clifford (Cliff) Olson, who says he was surprised to hear the actress’ voice when he answered his phone recently. The Olson outfit, a pale pink suede suit with a matching suede camisole, comes from the Mr. Frank shop in West Hollywood, Olson says. “It’s for Donna to wear on an episode of ‘Knots Landing.’ ” (Mills is a regular on the TV soap.) “But she was afraid suede would be too hot to wear under the stage lights,” he says. “So I suggested silk or lace instead of the suede camisole. She could get away with lace.” But will she dare? “I’m not sure,” Olson says. “I’ll have to watch the show to find out.”

For a story on “The New Society,” she was immortalized on the cover of Time magazine dressed in her riding clothes, faithful pooch at her side, standing in front of her home in Old Westbury, Long Island. But that was more than 20 years ago. Today, C. Z. Guest is still a model of horsy high society and understated chic, and if all goes well, next spring she will be manufacturing her look--”that classic sleek look,” as she calls it--under her own label, C. Z. Guest Style. Her cashmere sweaters (“I only wear cashmere myself”) were already unveiled at Adolfo’s recent fall collection in New York, where they were shown knotted around the shoulders of models wearing his suits. Contacted at her farm, Guest said she will only sell what she likes to wear. “I don’t like loose bulky clothes. I don’t think people should wear sweaters eight sizes too large or skirts down to their ankles. I wear them to my knee and have a swinging look. I like tight-fitting sweaters and slacks that show off the body.” Guest’s business manager, Pearl Bedell, also said there may be C. Z. Guest seersucker jump suits and aprons for working in the garden, one of Guest’s grand passions.

A lot of people say they can perform their jobs with their eyes closed. Well, Beverly Hills hairdresser LeMaire (of the salon of the same name) just did. For the movie “The Legend of Billie Jean,” LeMaire was called in to cut actress Helen Slater’s waist-length blond locks. The plot has Slater playing a small-town girl enmeshed in a battle between right and wrong. As an act of defiance, she takes scissors and cuts off her own hair. Enter LeMaire. To make it look as though Slater cut it herself, LeMaire says she shut her eyes, twisted the hair in her hands and “hacked” it off with a razor and thinning shears. Following a recent screening, LeMaire claims women were coming up to her and requesting a similar do. She sees the hacked-off look as somewhere between punk and “the perfect little haircut.”

It sounds like something out of “Dynasty,” but this soap story is about real people and real soap. Beverly Hills hairdresser Betty Pehrson reports that a woman who goes by the name Baroness Jordana Von Spiro (“she’s one of, I guess, the German families’ baronesses,” Pehrson says) flew to town recently from London to treat herself to one of Pehrson’s “air perms.” Von Spiro told Pehrson that she had read about the technique--which uses no neutralizers, but rods must be left in place for 24 hours--in a London fashion-magazine story that was illustrated with a permed Donna Dixon. “She says she lives a busy life and was very bored looking the same way all the time,” Pehrson says. So off the baroness went, lodging herself in L’Ermitage hotel and arriving at the salon wearing a baroness-like tight blond ponytail. She then returned to the hotel, spent the night with her perm rods in place and returned to the salon the next day to have her new curls unleashed. But before she jetted off to her next destination, she wrote a thank-you note on L’Ermitage stationery and had it hand-delivered to the salon.

Stephanie Williams, one of the stars of “The Young and the Restless,” says the clothing collection that will bear her name will not be for the Amy Lewises of the world. Lewis, Williams’ TV alter ego, is the conservative, goody-goody type of dresser, she says. And the Stephanie Collection of dresses, skirts and jackets, which will be in stores next summer, is not for the faint of heart. “We’re dealing with a lot of skin--bare shoulders, bare midriffs, bare backs. Lots of back,” she says. “I’m the free, sassy, sexy and sophisticated type.” The clothes will be designed by Wayne Spears, one of Williams’ old school chums from University City High School in St. Louis. Williams, however, says she will have a hand in designing because “it has to feel good on my body.”

There’s no reason why the “Anne Cole at Robinson’s” billboard should be so eye-catching. After all, it’s just a picture of another pretty girl in a bikini. But there must be something special about this King Kong-size rendition of the All-American dream girl, reclining on invisible sand with a face as California-wholesome as orange juice and sunshine. In any event, we noticed the billboard the other day while driving on a Downtown Los Angeles street, and it grabbed us so strongly that we almost crashed into the blue Datsun in front of us. Now we find we are not alone. The Register of Orange County has received an irate letter from Irvine resident Ditas Esperanza, which we quote: “I think Robinson’s department store should be issued a traffic citation for adding to the already heavy traffic pile-up, which occurs in the vicinity of the southbound Newport Freeway as it becomes Newport Boulevard in Costa Mesa, for their billboard advertising Anne Cole bathing suits.” We phoned Robinson’s to ask whether they got cited and found out only that the billboard has been moved to Downtown Los Angeles, which is where we saw it. All of which proves that, women’s rights notwithstanding, a pretty girl still stops traffic.

‘He knows his hair so well he could cut it himself,” but George Hamilton’s hair stylist, Janis Buller of the Vidal Sassoon barbershop, says her regular customer came in recently for a whole new look to go with his new role as a regular on “Dynasty.” “The part calls for George to wear a lot of hats,” she says. “So we cut his hair short around the ears and longer on top. He wanted to be able to flick back the top.” Fear not, fans. Hamilton may have given up some hair for show biz, but not a shade of his perennial bronze glow. Buller says: “He wouldn’t be George Hamilton without his tan.”
