I don't really know why there's such a call for such and such a kit. All I personally would like is something that doesn't make us look like a pub team out on a Sunday kickabout, like the present Home kit leans towards. If that means stripes, OK, but please, make them look good, so that when the players come out the tunnel there is a sense that they are already at an advantage. Recent examples of this were the Brazil kit, or the Championship striped kit at times, or dare I say it, even our present Away kit. My preference for a new Home kit based on the Florida/Xerox design is simply because I thought that one made the players look great, and balls to so-called traditions.
As for personal wear by fans, I have 3 Saints shirts, 2 England shirts and 1 Chelsea one [my 99 year old Mum still persists in thinking I'm a Chelsea fan - it's a long story if you haven't read it, PMs only]. The best looking one is probably one of the England shirts. Simple, elegant and very good for including in summertime sailing gear.
But the thing is, wear what you bloody well want, and if that is a Saints shirt from the 1920s then that's your choice. I don't wear my 1990s and 2003 shirts because I look like a berk in them. I look OK in the England shirt previously mentioned.
