Packers jersey can get as bad. The most obvious sign is the numbering on the back. If the material of the numbers look warped, it's a counterfeit. Good luck putting those things through the wash too. Most of my friends who have bought jerseys off of eBay (obvious counterfeit) have had the seams falling off by the second wash, and the numbers heavily warped. Brewers jerseys are more obvious. The 8's often look ridiculous, and the name on back is either too thick or too thin. I've seen some that are obviously the wrong font. Another obvious sign is the coloring. The gold stripes and number/name outlines should be a textured and shiny gold. It should never be a solid color. Many of the counterfeits have an obvious Packer-gold for the sleeves, which look absolutely ridiculous. There's also problems with the color of road grays and colors in the throwback. If you buy a Chinese counterfeit, you're committing a crime. It's illegal, hands down, no way to justify it. It's the same concept as bootleg DVD's. Not legal. If the seller claims he's legitimate, you're still doing something illegal. I'm not going to go out and buy an official $250 jersey. I have, however, bought legitimate replica Magestic jerseys for $60-$70. These look much better than any Chinese knockoff you'll get online, and they'll last a hell of a lot longer. They're not 100% true to game worn uniforms, but you're guaranteed proper stitching and coloring... and your numbers won't warp. It's kind of ironic that MLB prides itself on using Majestic jerseys, which are made in the USA. The cost is much higher due to this fact, and people turn to China for the uniforms anyways. And I really do think many people would complain if MLB switched to Nike or Reebok, or Majestic moved jersey production outside of the US. Many of these same people probably would own cheap knockoffs from China. As far as jersey sales go, I wish MLB would drop prices in their official uniforms so people could actually think about affording what the fans wear instead of resorting to buying obvious fakes. I'd comfortably say that 90% of 'authentic' jerseys on gameday (worn by fans) are fakes. Sure, they're never going to attract the guys that buys $20 jerseys, but they would get a lot more people buying authentic jerseys if it were priced reasonably. Enough to move 0% profit counterfeits over the current profits of authentic jerseys. If you dropped the price in half, I honestly think they'd get 5x more in sales, which would end up in more profit. This, of course, is hard to do considering the royalty system of a uniform. From production of a finished jersey, Magestic gets a cut, MLB gets a cut, the Brewers get a cut, and the seller finally gets their cut. By the time the seller gets it, they have to mark up to a ridiculous price to make a profit. Enough rambling.
