Hall was born in Gonzales, Texas, the daughter of Marjorie (née Sheffield) and John P. Hall, a truck-driver. She is of English descent. Hall was raised in the Dallas suburb of Mesquite, Texas, where she graduated from North Mesquite High School. She also attended Kim Dawson Modeling Agency. She has a twin sister, Terry, along with three older sisters; including actress Cyndy Hall. Following a car accident, she used the insurance money she received to move to France.
Hall was staying at a hostel on the French Riviera when she was discovered sunbathing on a Saint Tropez beach by a fashion agent, Claude Haddad. She moved to Paris where she shared an apartment with singer Grace Jones (who at that time was also a model) and immersed herself in the Parisian nightlife, often performing risqué cabaret acts in clubs and parties with Jones. Soon after, she moved in with fashion illustrator Antonio Lopez and her modelling career began. In 1975 she appeared, in the guise of a mermaid, on the cover of Roxy Music‘s album Siren. Five months later, lead singer Bryan Ferry gave her an engagement ring. Her relationship with Ferry continued and she also appeared in the video for his 1976 solo hit “Let’s Stick Together”. By 1977, Hall had been on forty magazine covers including Italian Vogue and Cosmopolitan. She was earning modelling fees in excess of $1000 per day.
Her trademark long blonde hair and height of six feet quickly made her one of the most visible and photographed models in the industry during that period. That same year, she met Rolling Stones frontman Mick Jagger at a dinner party in Manhattan, for whom she would eventually leave Bryan Ferry. Hall and Jagger were seen together constantly around New York, frequenting trendy nightspots such as Studio 54 and 21 Club. The Rolling Stones song “Miss You” was written by Jagger for Hall (many years later, Hall was also the subject of the Bryan Ferry song “Kiss and Tell” following the publishing of her 1985 autobiographical exposé Tall Tales that included details of their relationship). Jagger’s wife, Bianca Jagger, began divorce proceedings as a result of her husband’s involvement with Hall. With the large fees she commanded daily as a top model, Hall was able to buy herself a 200-acre (0.81 km2) ranch in Lone Oak, Texas. On March 2, 1984 in New York City, she gave birth to a daughter, Elizabeth Scarlett, the first of the four children she would have with Jagger. She continued her high-profile modelling career and later moved into acting and television work.
