I couldn't care a jot, i buy them and wear them as casual clothes, football shirts last forever and i've bought every shirt for the last ten years or so, i wear them to work and they last longer than normal work clothes, only rule i have is i dont wear the new/current season to work until the next ones are released.
You like and can afford you buy, you no like and cant afford you dont buy.....seeing as i dont buy many other tops now i'm a bit older and dont go out as much as i used to (have kids), i just buy these as usual clothes to wear....
