Petra Nemcova

Petra Nemcova showed her support for Diesel's Spring 2013 show at New York Fashion Week in a black leather jacket ($995), cobalt coated jeans, and a leather envelope clutch ($420), all by the label. The model's landscape graphic t-shirt broke up her textured separates, while her gold and black Jean-Michel Cazabat cap-toe pumps injected the perfect amount of sparkle. A silver bangle, wing-tipped eye makeup, and an intricately braided updo rounded out her fashionable ensemble. Steal Petra's street-chic look with her exact topper, blue coated jeans, a white graphic T, and cap-toe pumps.

Flat loafers are all the rage these days, but those who want height with their preppy choose high-heeled and platform loafers. Check out Alexa Chung wearing gray suede high-heeled loafers at the 2012 Scottish Fashion Awards, actress Olivia Thirlby rocking a pair of bright-pink platform loafers with a blue shorts suit, and model Petra Nemcova in colorblock high-heeled Tommy Hilfiger loafers. This trend is perfect for work, and as you can see from these three ladies, it looks great with everything from dresses to suits to pants. Opt to go bold in a colored pair like Olivia, classic in a neutral hue like Alexa, or funky in a two-tone pair like Petra.

Giorgio Armani will partner with actor Sean Penn to raise money for Haitian charities at the Cannes Film Festival.

Armani is sponsoring Penn's fundraising dinner Haiti: Carnival in Cannes, which Penn will host on Friday with model Petra Nemcova. The dinner's proceeds will be donated to Penn's Haitian Relief Organization, Nemcova's Happy Hearts Fund, and Artists For Peace and Justice.

"I am proud to stand alongside Sean Penn, a man cut from a very rare cloth," Armani said. "It is an honor to be a part of Sean's remarkable life of service by joining his humanitarian efforts for the people of Haiti."

In the past, Armani has supported charities like UNICEF, amfAR, and the Global Fund. In 2002, he was named a Goodwill Ambassador for the Office of the United Nations High Commissioner For Refugees.

In honor of Earth Month, Josie Maran (pictured left) is rereleasing her eponymous brand's cult favorite argan oil with an added charitable element. The beauty entrepreneur even recruited some of her model pals, Petra Nemcova (pictured right) and Angela Lindvall, to design the limited-edition bottles ($52 each) for the line's Model Citizen campaign. Available at Sephora, through QVC, or on Josie's site from now to mid-Summer, 10 percent of the profits from the sale of the oils will benefit the Happy Hearts Fund (through Petra's design), Healthy Child Healthy World (through Angela), and Women For Women International (through Josie).

Additionally, Josie and Petra are sharing their tips for going "chicological" (that's chic, high-performing, and ecological) with us. For starters, "I think using kinder, gentler, healthier ingredients overall — especially if you're wearing makeup every day — makes a huge impact on the beauty of your skin," explains Josie.

While checking out the Diesel Black Gold Fall 2012 collection at New York Fashion Week, Czech model Petra Nemcova showed us a new kind of edgy. That is, that the look doesn't have to mean all-black, ripped jeans, and caged booties. Even white jeans — when baggy and pulled up like Petra's pair — and shimmer can be badass when they want to be. To achieve this new kind of polished edge, a black leather jacket is necessary to balance the feminine pieces. Then wear a shimmery tank, white jeans — if you don't have a slouchy pair, rolled-up skinny jeans work, too — and a pair of unique ankle-strap sandals. Don't forget to finish the look with a dark metallic bag, like Petra's green satchel, for a pop of color. Wear this to your next nighttime outing and you'll make guys stare . . . and girls jealous.
