Maggie Gyllenhaal has been named as the first female brand ambassador for the menswear line Eton

Janelle Hallberg, brand and communications director at Eton, said: "Maggie embodies everything we admire: intellect, and an instinctive sense of style.

"She represents the shift in menswear - a move toward deeper cultural resonance, individuality, and relevance - and brings that clarity to Eton."

Maggie had no concerns about fronting the campaign as she regularly wears men's shirts.

The Crazy Heart star explained: "I actually am someone who wears men's shirts. So I thought it was a cool and unusual ask that I would represent them. Classic shirting is just part of something that I like to wear all the time."

Gyllenhaal explained that she likes to wear "oversized" shirts reminiscent of the 1970s.

She added: "I also like when they're soft enough, or thin enough in the fabric, that you can still see your body underneath or at least feel your body underneath. I love a collar, too. A strong collar. I like a little '70s."

Maggie feels that women are able to wear traditional menswear garments "in a way that's still very feminine".

The Dark Knight star explained that she has fond memories of fashion from an early age.

Gyllenhaal said: "It's funny - my mom always says her memories are tied to food, and mine are tied to clothes.

"I have memories from a very young age of either feeling like I had totally the wrong outfit on or, conversely, feeling like I was in just the right thing.

"One moment that stands out: I was in elementary school and obsessed with Cyndi Lauper. I dressed like her one day - wrapped a piece of tulle around my head in a giant bow, covered one eye, and felt amazing. Of course, I think I had to play volleyball that day and was absolutely not dressed for it. But still, it was a risk, and it felt great."

Maggie revealed that her passion for fashion has continued into adulthood.

She said: "It makes me feel good when I'm in something that feels like, at least in some way, it's an expression of who I am and how I'm feeling that day. And lately, there's a men's dress shirt."
