When any sports team wears a "retro" uniform that really isn't retro: they don't follow the proper style, or they add a bunch of old stylings and call it "retro".
The Bills current uniform could be considered a fauxback, since it's just retro styling and not an actual throwback to a specific era.
Uniphile: Those Dodger powder blue throwbacks are really fauxbacks...they aren't made of Satin!
Fan: Uhm...I don't really care. It looks nice.
