RSL's kit is quite subtle, but it kinda works. I liked the details on the collar. I'm not so sure the crest and manufacturer logo on the shirt would actually look good in real life, but I'll give it a chance.
Rabbi's kit is a difficult one to evaluate. Since Brazil has always worn simple kits, I understand it's very hard to design something out-of-the-box. Having said that, I think that the shoulder panels could be a little bit better. Also, the CBF watermark under de back number is, IMO, unnecessary.
All in all, I think that the design provided by [b]RSL[/b] looks better.
The Netherlands kit is very basic but doesn't suffer from it. The Brazil is a nice kit in its own right, I but a little too much going on for a Brazil shirt for my liking. I vote for RSL.
I don't like the green on the shoulders of the Brazil kit.
The thing about Netherlands is that not much can be done and honestly not much has to be done, just like with England's kits. The thing I like about the NED kit is the collar which is something new for it and is enough to get my vote.
