[4][5] Tinling designed a wedding dress for the British two-time Wimbledon singles champion, Dorothy Round on the occasion of her marriage in 1937.

The last Wimbledon champion to wear a Tinling creation was Martina Navratilova in 1979 when she wore his designs to triumph in both the singles and doubles events.

[7] He continued to design daring and unusual dresses for stars such as Martina Navratilova, Chris Evert, Evonne Goolagong and Virginia Wade throughout this time but his role in the infrastructure of tennis became more important and he became an official media spokesperson for the game.

[8] This led to Wimbledon chairman Sir Louis Greig to become furious with Tinling for "having drawn attention to the sexual area".

[9] He was banned from the tournament for 33 years, only being invited back on the grounds of the All England Lawn Tennis Club in 1982, when he retook his position as player liaison.

While the Wimbledon officials accused Moran of "putting sin and vulgarity into tennis",[11] the media dubbed her "Gorgeous Gussie".

[20] Tinling has been portrayed in two movies concerning the Battle of the Sexes tennis match played in 1973 between Bobby Riggs & Billie Jean King.

In the 2001 TV Movie When Billie Beat Bobby, he was portrayed by American actor Gerry Becker[21] and in the 2017 cinema release Battle of the Sexes, Tinling was played by British star Alan Cumming.
