Style according to Rachel Bilson

Our March cover girl is one of the chicest celebs in Hollywood, and here she lets Cosmo in on all her fash secrets.

Rachel Bilson is a pocket-size goddess of sartorial style – she’s just 1.58m tall – and she rocks a fitted black blazer like no one else in Hollywood. As far as we’re concerned, RB doesn’t put a dainty, size-five foot wrong when it comes to fashion.

Reminiscing about her time as Summer Roberts on The O.C. gave us a serious case of teenage nostalgia, but we’re glad she’s swapped skimpy-cute for understated chic. She always makes our Best Dressed list – and the perfect accessory to her look has to be her laid-back, be-yourself, who-cares attitude. She recently outed herself as a Justin Bieber fan (she blames her little sisters), and her dearest wish in life is to have the rotating closet fromClueless. And wouldn’t it be full of fabulous clothes!

“I have pea coats, menswear-inspired outfits, motorcycle jackets and flowy, feminine dresses,” she says.

“If I had to choose just one outfit to wear forever, I’d go for a long floral dress with my Balmain leather jacket and lace-up booties. But I usually wear jeans, a cosy knit sweater and boots, though. Shoes always come in first – but now I’m able to design to fill what voids I find in my closet!”

Yep – if she can’t find the right shoes, Rachel whips them up. The Hart of Dixie star has teamed up with celeb stylist Nicole Chavez to release a line of footwear for fashion site ShoeMint. We love that she’s so dedicated to elegance she’ll roll up the sleeves of her tailored silk shirt and get to work!

Her simplest style secret? “Go for neutrals, with a pop of colour.”

Given the star’s comfy-chic style, designer credibility and endearing nonchalance, we’ll be taking that advice straight to the shops. Got to trust the girl – she is tight with fashion royalty Karl Lagerfeld, after all.

Rachel covers the March issue of Cosmopolitan.

Picking the perfect sunnies

“I have a smaller face, so Wayfarers work because they have a small frame. If you want to try big ’60s frames, you kind of need an angular face and a good nose.”

On her street style

“I really just like to throw things together and be comfy. I’m a casual dresser. I enjoy mixing and matching and layering – just throwing things together. So it’ll be a mash-up.”

On her friendship with Karl Lagerfeld

“He’s just so warm and approachable. I want him to come over [to my place] and help me throw out scarves!”

On refusing to dress for men

“I know men hate harem pants, but I don’t give a sh!t.”

On smart casual

“I like that you can rock a shorts suit in autumn – you have a jacket, and you can wear a sweater.”

Her favourite fashion staple

“A classic, perfectly fitted black blazer is important. And I’m a really big accessories person.”

On her best-kept fashion secret

“I know nude shoes really help my child-size legs. You know, it helps in that area – you learn little things like that.”

Rachel’s top style tip

“Wear what makes you happy, and don’t put too much thought into it. You can’t pay attention to criticism, it’s not healthy.”
