when I first saw the yellow outfit, but I've grown to like it more now. I think it works better in a sunny, outdoor court in Australia than on the indoor WTF one too.
I first saw the black/yellow outfit from a seat high up at the O2 when Andy played Berdych. I couldn't work out what was going on with the top - it almost looked sleeveless, with some tattoos or lacy stuff on the arms. Together with the black shoes and ankle braces, which looked more like boots, I thought he's have fitted in well at one of my son's rock gigs in Camden!
Once I saw it closer up on screen it made more sense, and I quite like it now. The yellow shorts and white top were awful though.
He did wear some flourescent orange shorts at the O2 the previous year (his match against Ferrer), which seemed to get toned down a bit for the AO, where I also grew to like his Noddy outfit.
