Once a pop star tops the charts and racks up the Grammy Awards, what's next?  A clothing line, of course.  The Seattle Times reports that Macklemore has launched a new line of baseball-themed clothing.

Macklemore, whose birth name is Ben Haggerty, teamed with the already existing company Ebbets Field Flannels to create his limited-edition line, which was inspired by the uniforms of teams from the 1940s.  Among the items: a black-and-cream jersey that costs $195, and a satin jacket that comes in black or red, for $150.  Don't have enough cash?  A baseball hat featuring the logo of Shark Face Gang, Macklemore & Ryan Lewis' fan club, will set you back just $40. 

Asked to name his favorite piece, Macklemore told the Seattle Times, "It’s tough to pick just one. I love the jersey, I love the jacket, I love it all.”  The mini-collection -- if there's anything after the June 12 launch -- is available at the Seattle location of Ebbets Field Flannels.

The rapper is a huge sports fan, especially of his local Seattle teams.  Last week, he threw out the first pitch at a Seattle Mariners game, and Macklemore bobbleheads were given out to the crowd.
