From Kate Moss to Cara Delevigne, their faces have been plastered across magazines, advertising bill boards and every catwalk the fashion industry can muster.
But the supermodels of today are lacking one important thing, according to a veteran of the industry: a smile.
Daphne Selfe, who is the world's oldest working model at the age of 87, said the models of the 21st century looked too "sullen".
Ms Selfe said she could not understand why today's crop of models tended to strut down the catwalk without smiling. Instead, she suggested, the young women should aim to look "pleasant".
She told an audience at the Cheltenham Literature Festival that her generation had begun their modelling careers with lessons on good manners, deportment and how to get into a sports car "without showing their knickers".
