Collaborating with leisure and sports fashion brand EXR KOREA for a second time, Wonder Girls have been chosen as the models for the spring/summer 2010 photoshoot. Previously, Wonder Girls modeled EXR's school merchandise, donning apparel, backpacks and shoes of vibrant colors and stylish design. They transformed into doll versions of themselves, portraying stiff poses and blank expressions while wearing bright-colored wigs. For the coming season, the pop quintet showed off a casual and sporty image in polos, shorts and caps for EXR Progressive. The photos that have been released provide a glimpse of the what kind of style to expect, wherein Wonder Girls are seen exuding a bright and bubbly aura that is closely identifiable to their personalities offstage--well, maybe except for Sohee. New member Hae Lim has cleaned up a lot as well. As we await for the rest of photos, here's a sneak peek: [gallery] With the new fashion line, could Wonder Girls break EXR's biggest sales record once more?
