Mosque manners

Day after tomorrow I'm going on a AUS-sponsored daytrip (FREE!) to the Sheikh Zayed Grand Mosque in Abu Dhabi.  Third-largest Mosque in the world and one of the most spectacular.  Here's the picture the University attached to the email confirming I have a seat on the bus.  Kind of makes it look like, as a guy, I have to wear either a dishdasha/keffiyeh, full suit, or clamdiggers.
