I have never been into wearing my colours, although I do allow for wearing a small pin badge. I have to say the home top and the away blue effort are absolutely awful this season. Hopefully the other merchandise will be decent.
I've always found kit wearing by fans a slightly odd thing. I assume it started around the 1970's when some footballers became 'superstars' (George Best and others) and Clubs began the commercial sale of replica shirts. I read recently in an old newspaper piece that in the 1930's some fans wore caps (flat caps presumably) in their team's primary colour. Then there were team coloured scarves, which I imagine have been around for nigh on a Century. Caps and scarves, fair enough. Helped to keep out the cold on the terraces. But shirts? I like a lot of things or people in life, but I don't want to dress like them. Indeed usually that behaviour is regarded as geeky - like the people you see at sci-fi conventions, or the 'super-fans' of pop stars. I've been a lifelong Charlton fan, but I've never felt the need to wear a replica shirt. Hey ho. To each his (or her) own I suppose.
There were a lot of full kit wa**era in Ibiza - most bizarre! , I would expect it on the party side of the island
