As The National Museum of American History adds Michelle Obama's second inaugural gown to the 'First Ladies' exhibition on its 100th anniversary, TIME looks back at the dresses that got rave reviews, raised eyebrows, and launched the careers of young designers.

Michelle Obama, Jason Wu, 2009, 2013

The sleeveless red, chiffon and velvet gown was paired with a diamond embellished ring by jewelry designer Kimberly McDonald and shoes by Jimmy Choo.

Laura Bush, Oscar de la Renta, 2001, 2005

The dress is an ice blue and silver embroidered tulle V-neck. She also wore de la Renta for a 2001 Vogue photo shoot and at the 2004 Republican National Convention.

Hillary Clinton, Oscar de la Renta, 1993, 1997

Clinton wore this gold lace dress in 1997, but she first met the designer at the Kennedy Center in Dec. 1993, when he pointed out that she was wearing one of his dresses, which she claims she did not realize at the time. De la Renta has described his "friend" Hillary as "a symbol of where women want to go."

Nancy Reagan, James Galanos, 1981, 1985

The designer and his staff reportedly spent over 300 hours embroidering the beads onto this gown, and some news outlets estimated that her entire outfit cost $46,000.

Jackie Kennedy, Jackie Kennedy and Ethan Frankau, 1961

The design of this off-white, sleeveless, silk chiffon gown with accompanying cape was based on sketches submitted by the First Lady.
