For apparel you'll get more wear out of, check out Alexander Wang's first-ever denim collection, Denim x Alexander Wang, which launches today. [WWD]

Each purchase from the collaboration benefits Midwives for Haiti, an organization that seeks to reduce infant and maternal mortality rates in Haiti. Catch a sneak peek below, and shop the charitable activewear at A Pea in the Pod or beyondyoga.com:
