Canada-born Scaasi passed away on Tuesday (04Aug15), according to Women's Wear Daily.

He was best known for dressing some of the most stylish Hollywood stars throughout the 1960s and '70s, including actresses such as Joan Crawford, Elizabeth Taylor, Lauren Bacall, and Barbra Streisand, who famously donned his sheer black pantsuit when she won the Academy Award for Best Actress in 1969.

Scaasi also outfitted some of America's First Ladies, such as Lady Bird Johnson, Jacqueline Kennedy Onassis, Barbara Bush, Hillary Clinton and Laura Bush.

Many of his garments have been donated to museums, including the Smithsonian and the Museum of Fine Arts, Boston.
