Jessica Alba "lives" in her Minnie Rose cashmere boyfriend jumper, according to the company's founder Lisa Shaller-Goldberg.
The 35-year-old The Honest Company co-founder, as well as 'Mad Max: Fury Road' star Charlize Theron, Brazilian supermodel Alessandra Ambrosio, Elton John and the Duchess of Cambridge are among Lisa's clients who love to wear the luxury sweater.
Speaking to PEOPLE magazine about her celebrity clientele and their favourite items from her fashion line, Lisa - who broke into the fashion industry at 28-years-old and invented the iconic Juicy Couture tracksuit - said: "Jessica Alba lives in our boyfriend sweater and requests it in all different colours, as does Charlize Theron, Elton John, and Alessandra Ambrosio.
"Kate Middleton was wearing us the week she got married, pushing a shopping cart in our ruffle shawl.
"Somebody said to me, did you see the 'Sex In The City' movie yet? Samantha is wearing our hooded duster when she's running on the beach.
"It's fun to see how well this brand has been received throughout three different generations. I don't know many people that can do that."
Meanwhile Jessica - who has partnered with DL1961 brand on her 10-piece fall 2016 denim clothing line, which will be available to buy in August - has revealed she is more concerned with having a derrière that is admired by her husband Cash Warren rather than a fuller chest.
Speaking previously about her most-desirable body part, the 'Sin City' star - who is famous for having a particularly perky butt - said: "Boobs come and go, but butts are always in. The butt's always been celebrated. I don't know one man that isn't into booty. And I feel like women, more often than not, women like their butts and it's more accepted (to have a big butt)."
