The question, “Which Jonas brother is gunning for his own fashion line,” assumes that you know the difference between the three, which we don’t—even with the picture above. But we do know that this one (Joe Jonas) was at the Calvin Klein men’s show in Milan last night.  A big deal!  Even for a brand that’s never had a problem attracting big name stars—every hot guy from True Blood to Gossip Girl with a summer blockbuster in between wants to sit front and center at their New York Fashion Week shows. The main difference between the Jonas and the Chace Crawfords/Ryan Kwantens of the world, aside from age, is this guy wants to start his own fashion line.  He told WWD, “I’d love to do something down the line with a designer.” Celebrity designer match ups are usually reserved for starlets—that’s why we have Bruce Willis fragrances—but Jonas looks stylish enough to pull it off.  And if you’re worried about who would buy it, there are apparently girls outside his hotel in Milan singing him to sleep all night long—we’re sure they’d line up for days.
