Fashion Week's It Girl: Sophia Bush

Day 1: BCBG Max Azria

"Fashion is really fun to play with because it's self-expression," One Tree Hill star Sophia Bush has said. This season, she expressed herself in the front rows of New York's most-exclusive fashion shows, wearing designer looks like this blush-toned ensemble from her pal, Max Azria. "[He] amazes me-he's just so talented," Bush told us. "Everything he makes is beautiful and every runway show he ever does I walk away feeling lighter and happier and inspired."

Day 2: Abaete

The actress wore a sheer print blouse and draped skirt from Abaete to the label's presentation. She likely found plenty of inspiration for her fall wardrobe: "It's exciting for all those coats and boots and hats to come out!"

Day 2: Rock & Republic

The petite star dressed down a little black dress and Jacob and Co. diamonds with an edgy motorcycle jacket. Along with the designers' more dressy looks, Bush has pledged her allegiance to Rock & Republic's jeans. "I thank these guys for cutting things so well for our female backsides," she once told People.

Day 3: Herve Leger by Max Azria

The One Tree Hill star showed up to support her friend Max Azria at the launch of Herve Leger by Max Azria. Bush wore a curve-hugging striped bandage dress from the line along with diamonds by Jacob and Co.

Day 4: Malandrino

The fashion enthusiast kept herself under wraps at the Malandrino runway show in a double-breasted white coat with military flair.

Day 4: Malandrino

"French women have that allure that everyone speaks about and Catherine [Malandrino], I think, really puts that in her clothing," Bush told us. "It's sexy without trying, it's elegant." Certainly the sheer purple minidress the petite star sported-along with Jacob and Co. diamonds-embodied all those qualities.

Day 4: Ports 1961

Bush made a quick change of hairstyle before the Ports 1961 show-her sophisticated updo and Jacob and Co. gems complemented the label's ladylike wool dress.

Day 7: Reem Acra

Bush took in the Reem Acra show in a sequined shift from the designer, Jacob and Co. diamonds and mile-high Louboutins. Luckily for her feet, she had a mobile dressing room. "I change in the car," she told People.

Day 7: Rebecca Taylor

Bush met the flashbulbs at Rebecca Taylor in a silky black sundress and Jacob and Co. gems. Although her fashion sense never faltered during her week in the front row, her vocal chords took a beating. "I did lose my voice earlier in the week, but I got it back," she told us.

Day 8, Marc Jacobs

The One Tree Hill star finished out her fashion week with a coveted spot in the front row of the Marc Jacobs show. She wore the designer's trenchcoat-inspired minidress, punched up with whimsical accessories from the line and Jacob and Co. jewels.
