Meerkatsu and Gawakato are two jiu-jitsu centric artists that each collaborate with a bunch of companies, most commonly Tatami. Search online for Tatami gear and any outlet that carries a lot of their stuff will have some good options for detailed rashguards and spats. MMAWarehouse.com carries a pretty wide selection; you can search by those artist names and you should be good. Scramble also has some cool spats, though the fit is a little wonky due to the panelling. Pony Club Grappling gear makes the most insane shit, but they're currently on hiatus as they relocate to Abu Dhabi. Like Fraser said, you'll never have to pay full freight if you just keep an eye on the BJJHQ daily deal.
