Gucci

There are hot Spring ads, then there are scorching ones. Can you guess which category Gucci falls in? One look and it's crystal clear, this latest ad campaign is on fire! Karmen Pedaru, Joan Smalls, and Hailey Clauson — and a handful of gorgeous male models — put on their sultriest moves for Mert & Marcus's lenses. Click through to see the sexy chic end result.

>> The deluge continues; after yesterday's introduction to the Spring 2011 Chanel, Tom Ford, and Marc by Marc Jacobs campaigns, today brings another onslaught — Karlie Kloss's third straight campaign as face of Christian Dior; a first look at Kasia Struss for Miu Miu (Sasha Pivovarova and Querelle Jansen are also said to have been cast by the label); and perhaps our favorite campaign of the season so far, Alex Prager's take on Karolina Kurkova for Bottega Veneta, left.

2010 was no small year for Puerto Rican model Joan Smalls. The woman known for her endless legs, powerful stare, and personal charm has walked the runway of every major fashion designer, including opening the Jason Wu and YSL Spring 2011 shows. Mario Testino, Steven Meisel, Patrick Demarchelier, and David Sims have all shot her in editorials. She appeared in Gucci's Pre-Fall 2010 ad campaign and just recently signed on to be the new face of Estée Lauder. Phew. And it goes without saying that she's completely stunning. Here's a slideshow of some of our favorite Joan Smalls moments thus far.

>> Spring may not be in the air just yet, but the Spring 2011 ad campaigns sure are: The new year brought the release of a bevy, including Abbey Lee Kershaw's Tom Ford eyewear campaign and a look at Louis Vuitton's latest trio — Raquel Zimmermann, Kristen McMenamy, and Freja Beha Erichsen. There's also a peek at Chanel and Burberry (minus faces Ines de la Fressange for Chanel and Jourdan Dunn for Burberry, whose images have yet to appear), plus Gucci and Roberto Cavalli, left, featuring Laetitia Casta and Malgosia Bela.

On dark, cold days, a little color injection is the best medicine for drab wardrobes. Gucci and Preen showed us how it's done in their Pre-Fall 2011 collections, mixing bright doses of color with neutrals like gray and tan. The radiant result proves that color needn't be worn only in the warmer months. Want to add color to your wardrobe? Check out five of our Fab looks, styled out just for you. It's time to break out that lemon yellow top and brighten your day (and ours).
