A good outfit flows, especially when you’re outdoors and there’s wind—when you feel like it's almost drying by itself. There’s a cooling sensation that feels good when your'e sweating. I need good socks, too; Uniqlo has great socks. It sounds small, but if you’re moving athletically, you need to have really good stability in your shoes.

We're moving to a new racket. Basically, we're putting on the tuxedo look a shirt. It is already my favorite racket. Hope you enjoyed!
