She is 20, gorgeous, the granddaughter of a Brazilian billionaire. Her mother and aunt were models, and she parties with only the coolest kids. She is the coolest kid. With a little help from Mario Testino and Carine Roitfeld, she channelled Jerry Hall in a glorious editorial in Paris Vogue. She’s the name on everyone’s lips, from Milan (Donatella!) to New York (US Vogue!). She is Alice Dellal at Select Model Management, and she is major.
