Nicknamed Twiggy as a child (her real name is Lesley Hornby), the 1960s supermodel is most famous for her thin build, but that doesn't mean that her hair didn't play a major part. The combo of her super short hair and uber long lashes resulted in iconic beauty images like this one!

"It was clear that we had to go short and create a new look that embraced her beauty, great personality and body" said Posh's hairstylist Garren, of Garren of New York.

When Evangelista first cropped her hair in 1988, she was cancelled from all her runway bookings. But don't feel too sorry for her! Two years later she told Vogue that she and supermodel pals Naomi Campbell and Christy Turlington "don't get out of bed for less than $10,000 a day."
