The bottom line of all of this is that whether or not the club notified people beforehand. (which they did PARTIALLY), you should be able to wear whatever the hell you like.
No one would dress offensively and enforcing a dress code is silly considering the amount of people in there who are just regular football fans. I'd dress smartly most of the time anyway, but on occasions where I'd just come from town or was out and about in shorts before the game, I would not take too kindly if I was refused entry to the stadium on these grounds. If you've I have paid for a valid match ticket is there a way you could avoid the lounge and only take your seat?
It makes me angry because there is simply no need for a dress code.
I guess the issue is that from reports on here anyway, they don't seem to be enforcing it. Will they really be bold enough to refuse entry to someone at 2:45pm on a Saturday because their attire is wrong?
It's the same as the kids/no kids thing at Dick's: Issue a clear message and then have the bollocks to apply it consistently to EVERYONE, even club 'friends'. No exceptions.
