usually a plain, solid colored t-shirt (although that has changed some recently)
shorts, usually non-name-brand - cargo or not, if they're comfortable
sometimes pajama pants
not really sporty
I have changed in shirt style some recently, though. I have lost about 40 pounds since nevember, and I've been working out more, so I've started wearing shirts that are more fit to me than most of my wordrobe that I had to hide my belly
I have skate shoes, but they're two yeas old, worn away like crazy, there is a big tear in the ollie zone on the right shoe....big, and right now they have a light layer of grass crusted on them because it's been grass cutting days, so you can't even really tell they're skate shoes any more....still hella comfortable, though
