Quote - A content creator who agreed to do these for pay would be potentially at risk of getting into hot water with the owners of the Star Trek franchise.  And, since making clothes ain't exactly a walk in the park, I doubt many would want to make 'em for free, unless they're a devoted Trekker.

Until then the alternatives are your best options. 

 

Dude it's Trekkie, Trekkers are just Trekkies in denial. :P
