Anything over about 16 then only acceptable if you move to a retro shirt.
Cue disagree ratings. ...3 ...2 ...1
Grown men, unless actually playing football should never wear a modern football shirt. Especially out to dinner when on holiday
Retro shirts, club polo shirts/ leisurewear is acceptable to show your support, but fitted football tops on overweight middle aged men and women is not a good look.
I know there will be a lot that take offence at this, please don't, it's just a personal pet hate of mine
