I think the US top is dreadful. Could do without the red collar and all the polychromy. But, yes, the sash is quite reminiscent of the shirt worn in 1950. I wonder if the design was chosen because the US is playing England in the World Cup.
It was.
And since I can't double quote, I'll just point out that the home jersey has been leaked, just not released yet.

Like that one much more than the Red one. The blue one is pretty decent though too.
