I noticed that too, it obviously works for him, so he should keep doing it lol.
I like the blue a lot. I prefer the black version, that's my personal view, but if I never see the white one again I'll be a happy woman. That said, it did look good in Australia, in the sun.
I never think if it as yellow in Andy's kit. I reckon, the next time they meet, he should let Federer know that it's a new shade known as Olympic Gold lol.
