Hayden Panettiere

We’ve already confessed that Rihanna is our latest fashion crush. And yet again, the singer struck a fashion high note — leaving her New York hotel toting this Kooba bag that accessorized her biker-chic look. Her Heather shoulder bag, trimmed with vivid day-glo piping, has a retro ’80s vibe that we love. You can order the same one, $465, at kooba.com, or nab a smaller version, the Bennie clutch, for a more affordable $295. And you’ll definitely be in good company — Jessica Biel, Jessica Alba and Hayden Panettiere have also been spotted carrying Kooba handbags.

The whales are not the only thing the Heroes star is trying to save. Hayden Panettiere also wants to save the planet. While tugging designer bags, like her Kooba Elisha tote, the budding humanitarian opts for eco-friendly clothing lines like her Gypsy 05′ hoodie. The Gypsy 05′ organic “French Rose” hoodie is made using fabric derived from bamboo, low impact dyes and a 90% organic printing process. We sense the young starlet is paving her way into Hollywood’s activist hall of fame–keep it up! We found Hayden’s eco-friendly looks– and her fab bag!

The Heroes star stepped out for a Pepsi party in Hollywood pairing her affordable French Connection tube dress with a pair of patent platform Christian Louboutins. We love how Hayden Panettiere mixes budget friendly finds with extra-special (and extra-expensive!) accessories. The young fashionista loves her Christian Louboutins just as much as her collection of Steve Maddens. We found Hayden’s dress and shoes — and a pair for a lot less!

Two of our favorite blonde TV actresses hit the streets of New York City this week in the exact same pair of boots — and we were so smitten we had to track them down! Hayden Panettiere paired her Coach “Weslyn” boots in Whiskey with a black peacoat for a day of appearances in the city, while Blake Lively was snapped on-set in character as Serena van der Woodsen in her brown riding boots. You can buy a pair of the actual boots for yourself, but if you want to spend a little less than the stars, we’ve got some more affordable options for a similar style.

Over last weekend, Lauren Conrad and Hayden Panettiere stepped out showing off shiny new bags, and it seems the two California girls have a lot more in common than just boys — both have dated Laguna Beach alum Stephen Colletti. They love the same black D&G purse! The Hills star brought her patent satchel shopping with her friends in West Hollywood, while the Heroes cheerleader lugged her matte bag to a studio in Culver City. We love how chic the bag looks with their casual outfits, but the price tag is way too hefty for us. Check out how to get Lauren and Hayden’s actual D&G lock satchel and some similar looks for less.
