Definitely an enormous pair of gold-rimmed traiditional 'aviators'. Probably with a flight suit and leather jacket if you can afford them...and don't forget to get some nice big gold wings to complete the ensemble.
In all seriousness, I've found that anything will do, even $12.00 servo sunnies. If you've got money to spare, I recommend some Serengetis or Ray-Bans. Provided you don't lose them, like I always do, they'll serve you well.
