What catchy name did the very first supermodel in London go by?

There isn't one definitive "first supermodel" in London or anywhere else. The concept of supermodel as we know it today developed gradually in the 1980s and 1990s.

However, some names often associated with the early rise of supermodels in London include:

* Jean Shrimpton: Known for her androgynous looks and breaking fashion conventions in the 1960s.

* Twiggy: A fashion icon of the 1960s, known for her androgynous look and her short, pixie haircut.

* Lesley Lawson (aka "Bird" or "Loulou"): A prominent London fashion figure in the 1970s and 1980s, known for her glamorous style.

Each of these women contributed to the changing landscape of the fashion industry, paving the way for the supermodels of later decades.

Remember, it's hard to pinpoint a single "first supermodel" due to the evolution of the term and the contributions of various individuals throughout history.
