Hot on the heels of Prabal's resort 2012 video featuring rapper Rye Rye dancing in the new collection, Alexander Wang has released a feel-good short headlined by another M.I.A.-approved high-octane act—Santigold. The men's and women's T by Alexander Wang fall '11 campaign video features the singer breaking a sweat with one-half of hip-hop group Spank Rock, set to an exclusive Switch remix of Santi's new single, "GO." The duo also stars in ads (above), shot by Dan Jackson and styled by Alastair McKimm, that are currently part of a wildposting initiative throughout the city. We suggest watching both designers' videos before heading out on the town (or to the gym); we won't lie and tell you we aren't moving around in our chairs right now.
