Donning scrubs on her TV show, Grey’s Anatomy, Katherine Heigl is far from a fashionista. Off the set, though, she’s got a great, easy style that always looks polished (to go with that nice polished rock she’s got on her finger).

Katherine isn’t a big risk-taker or a trend-setter when it comes to fashion, but she knows how to put together an ensemble that highlights her curvaceous body without going over-the-top on the sexy factor. Add that with her magical ability to mix prints and colors and you’ve got yourself one fashionable lady. She’s often photographed around L.A. in adorable sweaters, flats and jeans, but when she hits the red carpet, she brings out the va-va-voom and plays up her blonde bombshell status with curve hugging, classically glamorous gowns. There is no need for a little lift or tuck in her wardrobe; this girl has got it going on.

Of course, no celebs are immune to the occasional “what the hell were they thinking?” moment, but for the most part, these celebs look foxy and fabulous and inspire us all to do the same.

My Style Idol of the week is someone who is one of the most popular young faces in Hollywood/the music scene right now. She does a great job of playing up her personality and youth whether she is heading to a red carpet event, or just hangin’ out.

Rihanna.

Okay, so I’ll admit: it bugs me that Rihanna is one of the biggest pop singers in the world when (in my humble opinion) she can’t even sing, but I cannot deny that the girl’s got great style. Admittedly, she does have occasional snafus, but overall she does a great job of putting together fun, funky and age-appropriate outfits. She’s a trend-setter and is great at picking out clothes that work well for her body type.

Whether glamming it up at awards shows or out and about with her “good friend,” Chris Brown, she’s constantly snapped looking hot as hell and flaunting her unique and eye-catching style. Not only does she change it up with bright colors and intriguing cuts, she’s also ahead of the curve when it comes to hair, make-up and nail trends.

No matter what, you can’t deny that Rihanna has an individual style that she owns and flaunts and that’s what being fashionable is all about.
