Julie Crosthwaite (also known as Julie Crosthwait) was born in July 1951 in Stroud, Gloucestershire, UK. She is an actress, known for Armchair Cinema (1973), The Picnic (1976) and The Protectors (1972).

She was on the first British edition of the Cosmopolitan in March 1971. The then twenty-one-year-old Julie Crosthwait was the model for the first issue cover taken by David Magnus. She was chosen by editorial director Helen Gurley Brown and told the Daily Mirror 30 years later (Feb 21): “I didn't live the Cosmopolitan lifestyle at all. I must admit I was a bit shocked when I actually read the magazine.”

She is 178 cm (5' 10") tall.
