Nick, send Muz a PM, his daughter Hannah wore hers at Spa last year, she's a couple of years older but not by much - Hannah must have a bigger wardrobe of race tshirts than most of us! See
http://www.clubarnage.com/forum/index.php?topic=8669.0 about four posts down, I think the sparky sunglasses are a must have item for this year for all female race fans!
I'm not sure i've got pics of me, I'm normally operating the camera and last year wasn't really tshirt weather!
