Max, the solution is to surf the wave of conformity. Once critical mass is achieved (50% +1?), the rest of the crowd will feel out of place and in lunch time, they will rush out to the nearest Hawaiian shirt store!
@Betajet: Mine is black with big yellow flowers. Very elegant. I'm glad to have a good opportunity to show it off :-)
I'm looking forward to seeing it. I will be wearing Hawaiian shirts throughout the conference (I wear them every day) -- and I would love to see other people wearing them throughout the conference -- but for those who have only one Hawaiian shirt (say a black one with big yellow flowers), perhaps the best time to flaunt it would be at the conference party on Tuesday afternoon (4:00pm to 5:00pm, I think).
Maybe we can have an unofficial competition to decide who is sporting the most bodacious Hawaiian shirt?
