British fashion designer Mary Quant , who revolutionized fashion with her contribution to spreading the mini skirt, has died at the age of 93, her family said Thursday.

The family indicated that Mary Quant, the prominent name in the "Swinging Sexties" cultural trend in the sixties of the last century, died "peacefully" inside her home in Surrey, southern England.

The family pointed out that Quandt was "one of the most famous fashion designers of the twentieth century and an exceptional creator."

Born in London on February 11, 1930, Quandt opened her first store in 1955 in the then-thriving Chelsea area. Soon, her clothing and accessories store was frequented by members of the "Beatles" and "Rolling Stones". Among the store's customers were the stars Brigitte Bardot and Audrey Hepburn.

Quandt is known for designing short dresses and skirts with simple lines and bright colors. She had a role in publishing women's shorts, raincoats, eye shadow and waterproof mascara.

In Quant by Quant, her first autobiography published in 1965, the British designer says, "My clothes turned out to be very teenage fashion, reflecting popular culture and the atmosphere of jazz clubs."
