I am a big fan of all things related to uniforms, so here are my two cents on this issue:
Is it a big deal? No. I THOUGHT I noticed something was different but couldn't say for certain. What it is though, is change for the sake of change and I am not really a fan of that. Paul Lukas over at Uni-watch has a good method of assessing uniform changes and that is: "Is it good? Or is it stupid?" I would argue that most changes for the sake of change are stupid. So it's not the end of the world and isn't really THAT big of a deal, but it is, well, annoying.
