We all love a good supermodel sighting, especially when she's shaking her money maker for a good cause. Yesterday, Doutzen Kroes was on-hand at the SOHO A/X Armani Exchange to launch the dance4life t-shirt ($35), which she co-designed with Mr. Armani himself. The catwalk stunner was on-hand to sign copies of the shirt and command control of a dance party to promote the garment.

The 100% cotton unisex t-shirt, which launches today on World AIDS Day, features a black-and-white photo of Kroes with the words “Dance-Dance-Dance” printed in bold red across the front. It retails for $35 and is now available in all A|X stores and online. 100% of the profits from the sale of the shirt will support dance4life education initiatives to inspire, educate, and mobilize the youth of the world to lead the global dance4life movement and stop the spread of HIV and AIDS.

You know you need a cute new shirt. Make like a supermodel and strut down to A/X Armani Exchange to show some love on World AIDS Day - and every day, for that matter.
