From the bright lights of Hollywood in the ’40s and ’50s to the political scrutiny of the White House in the ’80s, former first lady Nancy Reagan has always had a signature style. With her secretarial bow blouses and elegant designer gowns, she “never made a single faux pas,” designer Oscar de la Renta told People magazine. In honor of her 90th birthday on July 6, The Daily Beast looks at Reagan’s top looks through the years.

As the eternal housewife on screen, she earned rave reviews among critics and eventually also from fellow actor and future president Ronald Reagan, whom she wed in 1952. Here, she posed in ’50s signature gloves and a boat-neck cocktail dress.

Despite their growing brood, both Ronald and Nancy were still working in front of the camera and smiling in their elegant ensembles at red-carpet events.

They took a trip to St. Thomas that same year, where the then first lady of California sported this pink, daisy-emblazoned swimsuit and matching hat.

Though he lost the 1976 Republican presidential nomination, the family enjoyed their time at home, riding horses and plotting Reagan’s comeback for the 1980 election. Bettmann / Corbis After Reagan won the 1980 election, he and Nancy toured the White House with then-President Jimmy Carter and then-first lady Rosalynn Carter on Nov. 20, 1980. The incoming woman of the house showed off her luxurious side in this fur-lined suit during her first post-election visit to 1600 Pennsylvania Avenue. Wally McNamee / Corbis After Reagan won the 1980 election, Nancy stood by him at his first inauguration on Jan. 20, 1981, in what was to become her signature shade. The color, which W magazine reported she has worn in 1966, was soon dubbed “Reagan red.” She later told W, “I always liked red. It's a picker-upper.” Corbis Nancy showed some shoulder in this striking sheath by James Galanos for her first inaugural ball. “She knew her style very well, and it was always simple and elegant,” the designer told the Los Angeles Times. The 59-year-old first lady brought a new wave of style to the White House in this embroidered lace asymmetrical dress, which reportedly cost $10,000.

As she has long taught us, when it comes to over-accessorizing, it is important to “Just Say No.” White House / CNP / Corbis For her second inaugural ball, after her husband was reelected, Reagan returned to old faithful: James Galanos. The 1985 gown, which was also slender and white, offered more coverage and just as much bling. Though there was a bit of criticism about Reagan’s glamorous wardrobe, the designer was quick to defend her. “My clothes are long-term investments,” Galanos told People magazine. “They usually end up in museums, too. Women who spend this kind of money understand.” Ira Schwarz / AP Photos During a Canadian-U.S. summit in March 1985, Reagan stood tall in this Adolfo gown, which cost an estimated at $6,000, beside Canadian Prime Minister Brian Mulroney and his wife, Mila. The designer and Reagan had a longtime style love affair. “I think she will always have an effect on fashion,” Adolfo later told the Los Angeles Times.

At a drug-abuse summit at the White House in April 1985, she said yes to both of her signature looks in this classic first lady ensemble.

How I wish I was one of those people who never lets anything show on her face,” Reagan told the Sun-Sentinel just a month later. AP Photos As the holiday season approached and the temperature dropped in Washington, D.C., in December 1987, Reagan pulled out her fur coat, as did the style-conscious first lady of the Soviet Union, Raisa Gorbachev. Though they reportedly had a fashion face-off, Reagan put the rumor to rest. “There are very important things being discussed here, and what somebody wears or doesn’t wear really isn’t terribly important,” she told Time.

Diana Walker / Time Life Pictures / Getty Images The Reagans reserved their first and last state dinners for British Prime Minister Margaret Thatcher. By the time their final event for Thatcher came in November 1988, Reagan had mastered more than her crimson wardrobe. “Presentation was everything,” the White House chef at the time told The Guardian. “Mrs. Reagan never told me how something tasted. It was always presentation—like a flower bouquet, the colors had to correspond. We knew that, so we proceeded like that.” Diana Walker / Time Life Pictures / Getty Images Though the shade of her dress at Forbes’ 75th anniversary at Radio City Music Hall in New York tends to signify friendship, Reagan’s relationship with Raisa Gorbachev reportedly remained frosty. Nevertheless, the yellow cinched-waist cocktail dress at the 1992 event was a welcome departure from her typically fiery wardrobe tone.

Bush at the British Embassy in May 2007. Despite her climbing age and great loss, Reagan demonstrated the unassuming grace she was renowned for.

She joined Obama at the signing of the Ronald Reagan Centennial Commission Act at the White House in June 2009, wearing a red suit and a smile. She is still, like President Kennedy’s wife, a beacon of first lady fashion and poise. “What is so interesting about Nancy is how she's grown,” jeweler Kenneth Jay Lane told W in 2007. “She was perfectly nice when I first met her, like many other ladies—comme il faut. She became more sophisticated, easier and looser, and always very kind.” Dennis Brack / Black Star / Corbis
