It's their first kit that is the centenary one really, hence the gold trim. Apart from also sporting the special centenary badge I don't think the change kit is intended to mark the 100 year anniversary,
The red kit was launched some weeks before the Red Dragons' monstrosity and seems to have been planned well before Vincent Tan's muddled, rushed rebrand. Certainly it looks like it's benefitted from a proper design process unlike "Cardiff's" botch job.
Oh no, it is certainly a nod to the national colours.
There's nothing wrong with that and while I think it might be a slight dig at Cardiff (rubbing in the fact that they are Wales sole EPL representative. Much like their tangerine change kit last season appeared to celebrate Blackpool's defeat of Cardiff in the 2010 play-off final) it's subtle enough to not be egregious.
They've certainly left all the upfront "We're the team of Wales" posturing to that bunch of twats down the M4. Crucially, it's also a lovely kit. Far better than the national side themselves have sported for quite a while.
Having been with the now almost defunct Umbro for many years, rumours at Forest is we are going back to Adidas. Hopefully they will take the opportunity to remake the old classic Clough era tops. The current official-fake ones have a Cruyff-esque two stripes.
In a similar vein to some colours in kits not quite matching. I hate seeing players with long sleeve undershirts on under short sleeved tops. If they want to wear undershirts that's fine, but they must be forced to wear long sleeved football shirts. End of. It is even more infuriating for me when the player is in a striped shirt, and wears a plain colour underneath. Like this:
I agreed with FIFA banning the use of white tape over coloured socks, and this is clearly the next step. Down with individuality, it's a fricking uniform.
