Rachel Bilson has long since left The OC behind, and has made a name for herself in the media as a fashion star, editor and advice columnist, as well as the style consultant behind the subscription- only shopping site Shoemint, run by Steve Madden and celebrity stylist Nicole Chavez. She has become the darling of the fashion crowd with her sweet looks and down-to-earth wardrobe. Her style is enviable and relatable because it is simple, casual and appropriate for school, work and evening social functions.

A typical day look that Bilson might sport would include a slouchy pair of boyfriend jeans; a long-sleeved crewneck top with a simple design, either striped or colour blocked; and a pair of lowheeled ankle booties in camel, brown or black. The best part of the look is that you can easily find the pieces at local stores and put it together yourself without spending a fortune on designer items and still achieve the same effortlessly chic look.

To amp up her day look for a business meeting or lunch date, Bilson is often pictured with a dark, structured blazer or refined leather jacket thrown over a casual look to give it more professional appeal. Swap out the crewneck for a sheer blouse, top that with a leather motorcycle jacket, and exchange the flat booties for metallic wedges and you can capture her edgy night-on-the-town look.

Of course, there are occasions that require a more formal outfit, and being a TV star and celebrity certainly prompts Bilson to don a few fabulous dresses. Her red carpet style runs the gamut from body-hugging mini dresses to bohemian-chic maxi skirts. Lately, Bilson's formal looks have been more streamlined and edgy. She always stands out in a crowd of gowns because of her individual style. Even when wearing a more mainstream look, she always inserts some element of her personal style, whether it comes out in the form of an edgy up-do or a tough pair of leather boots worn with a girly printed sundress.

Bilson's beauty look also suits her laidback style. Her unfussy, wavy but not overdone hair always tumbles over her shoulders. Recently she has been seen sporting the ombre hair trend, where the tips are slightly lighter than the roots. This look is the epitome of casual cool, and Bilson is definitely too cool to worry about missing a dye job every now and then.

Of course, in keeping with the rest of her ensemble, she doesn't overdo it in the makeup department. A clean, fresh face, rosy cheeks and lips and natural eye makeup suits her everyday look.

It is easy to be inspired by Rachel Bilson's wardrobe choices. Take a cue from this style maven and keep it simple and laid back. Make sure that what you are wearing suits your body type and your personality, and always add your own little touches to make the look your own. If we have learned one thing from Bilson, it is the value of looking put-together simply and effortlessly. After all, no one wants to look like they're trying too hard!
