Is it okay to wear a different type of brand of motorcross gear than the brand of your bike?

I have a kawasaki kx 100 motorcross and i can seem to find a kawasaki jersey or pants or glove or a helmet. So im wondering is ok to wear a different name brand as long as its green or would that be weird. I would like kawasaki so if you now where i can find some on the internet please give me the link or tell me where you can find i can find some on the internet. And if you dont have either of them please tell me is it ok to wear a different name or not,
