Irina Dobrynin is already in the Crimea, where her husband will join her later this month. Once he arrives there, Soviet Ambassador Anatoliy F. Dobrynin says he expects to swim every day, getting "in condition" for fall when, among other contests, his boss Leonid Brezhnev and Ronald Reagan are expected to square off on a variety of topics if the proposed summit meeting takes place.

"I never complain about lack of energy," says the dean of Washington's diplomatic corps, "just where to apply it."

Nancy Reagan has sent a second batch of her controversial designer clothes to selected American museums where students of costume and design someday may be able to study their construction and historical significance.

For the moment, however, none of the museums has any immediate plans to exhibit the clothes, according to Ann Keagy, who will continue to administer the program, even though she resigned June 30 as head of the Parsons School of Design design department.

Keagy said yesterday that all 13 museums she selected last winter to receive the first batch of Mrs. Reagan's clothes now have deeds of ownership to the garments signed by the designers.

"The whole first shipment has been accepted," said Keagy, who received a second, smaller batch of Mrs. Reagan's clothes a few weeks ago and has already shipped them on to about six museums. She said she did not know when--or if--the first lady will send a third batch for her to distribute.

"Usually I just have a day's notice," said Keagy. "They the White House call to make sure I'm in to receive them."

At the Museum of Fine Arts in Boston, where the permanent textile galleries have been closed for renovation since 1979, acting curator Catherine K. Hunter said there are "no plans" to exhibit a red silk suit by David Hayes.

According to Hunter, Mrs. Reagan wore the suit on May 11, 1981, to a luncheon given by Beryl Ann Bentsen (wife of Texas Sen. Lloyd Bentsen) and to two back-to-back White House receptions (one for Congress, the other for Wolf Trap). Some weeks later she wore it again on three flights to or from California aboard Air Force One.

Hunter said the museum was given no choice of garments and that when the suit is exhibited the credit line will read: "Gift of Nancy Reagan and David Hayes."

Reached at his design studios in California, Hayes said Mrs. Reagan purchased the suit but had put his name on it as a donor. "I think that's nice, don't you?" he said.

Mrs. Reagan first offered some of her clothes to museums last winter after it was disclosed that she had been accepting them as gifts from leading American designers. Later, calling the clothes "loans" rather than "gifts," White House aides devised the museum project as a way to minimize the effect of adverse public opinion. It also spared the first lady the need of declaring the value of the clothes as income.

Yesterday, Keagy said the designers gave the clothes to the museums "purely as a donation. They didn't want any tax write-off. So far as I know, none is taking any write-off."

Asked if she considers a garment worn at a reception, a luncheon or on a plane trip to have historical value, Keagy said, "Yes and no. It's historic when you think there are presidents' wives about whom we have no information at all. To people who do research, these things are important."

The Washingtonian's current list of "best" and "worst" of the Reagan administration rates Deputy Secretary of Defense Frank Carlucci III as very short, indeed, on a sense of humor. Maybe that's what happens when you become important. But back in the early 1960s, when Carlucci was a young, tough, very able U.S. Embassy second secretary grappling with the spread of the Cold War to Africa, he was noted for his "vivid and often hilarious accounts of his experiences in Stanleyville, which bore a striking resemblance to Evelyn Waugh's satirical novel 'Scoop,' " writes Madeleine G. Kalb in her new book, "The Congo Cables."

In Leopoldsville, where the impetuous Patrice Lumumba governed by press conference, Carlucci got some of his own scoops for the State Department by flashing a press card and pretending to be a journalist. After Lumumba's downfall his government fled to Stanleyville, and one of Carlucci's jobs was to keep track of the rebel politicians. Kalb thinks he may have scored a diplomatic first on one trip there when he was invited to the minister of justice's hotel room to discuss American aid.

As Carlucci later described the scene in one of his famous cables, he wasn't the only visitor. "An attractive young Congolese lady," apparently bored with such serious talk, "stepped behind a curtain, undressed and fell on the bed, covering only the bare essentials with part of her skirt." And that might have been Carlucci's exit cue, except that after some pounding on the door an unidentified Congolese came "bounding in, shouting that he wanted to see his wife." He didn't get to see her long because police soon carted him off, as Carlucci later observed, "probably never to be heard from again." Ever unflappable, diplomat Carlucci went right on discussing aid--and sipping his beer.

The next Falklands? How about Diego Garcia? Mauritius Ambassador Chitmansing Jesseramsing says U.S. expansion of its military base on the wishbone-shaped British-owned atoll in the Indian Ocean is causing his government serious concern. Jesseramsing, who long has been seeking return of the island, said Mauritius will use a campaign of "consciousness-raising" within the international community rather than resorting to force. Probably a wise decision; unlike Argentina, says Jesseramsing, "we do not have a navy to go in and invade it."
