Which model was first to have her own clothing line?

It's difficult to definitively say which model was the *absolute* first to have her own clothing line, as the concept of models designing clothing has been around for a while and records aren't always perfect. However, some of the early and notable examples include:

* Twiggy: Considered a fashion icon of the 1960s, she launched her own clothing line in the late 1960s, which focused on youthful and modern designs.

* Jean Shrimpton: Another iconic model of the 1960s, she also had her own clothing line, which included both casual wear and more formal pieces.

* Lauren Hutton: A prominent model in the 1970s, she created a successful clothing line in the late 1970s, known for its casual, sophisticated style.

It's important to note that many other models have launched their own clothing lines over the years, with varying degrees of success. Ultimately, the "first" model with a clothing line is a bit of a grey area, but these names are among the most prominent early examples.
