Just got my $13 jersy from aliexpress, and it's not bad. The zipper isn't great, and the small details aren't great, but for the price it's pretty damn good I think. Definitely the $75 name brand jersey I got is nicer, but we will see how they perform when I'm on the bike.
FWIW, the expensive jersey is better looking on me, but I got to choose that one in the shop.
