The gear you need.
I always used a ball cap but you have to break off the little button on top as the headset will drive it into your skull and it will hurt....a lot. Good pair of glasses with some thin arms, comfortable pair of shoes (do NOT EVER wear sandles or loafers) just runners or hiking boots, an E6B is handy to have. If you are serious look into a helmet but I wouldn't rush out and buy one as they are not cheap.
More important is how to prepare for your flight, make sure you understand what is expected of you and review it the night before, get a good nights sleep and eat a light breakfast like yogurt, a bannana, and a gronola bar, stay a way from acidic drinks, acidic fruits, no eggs or milk.
