She hasn't exactly got it right every time, but it seems that when it comes to Anne Hathaway's favourite style icon, Catherine the Duchess of Cambridge can do no wrong.
The actress has praised the princess for her "ladylike" dress sense, telling USA Today she was setting the standard for a new "anti-Hollywood" look.
"Can I tell you how grateful I am to Kate Middleton? Because she is such an advocate for dressing like a lady," she said.
"I think for a few years that kind of slightly dirty look was adopted by Hollywood you know, the stringy hair, homeless thing."
Despite trying this look herself, the 28-year-old actress says she couldn't pull it off and it made her look "chubby".
"I was like okay, I'm going to give that a go. (But) it doesn't suit me, I don't suit it," she said.
"I always looked kind of chubby."
Anne, who is dressed by celebrity stylist Rachel Zoe, says she is now basing her look on Catherine's style.
"I'm just very grateful to Kate for making looking appropriate really fun again," she said.
"So right now my fashion choices are all about Kate Middleton."
