Appropriate accessories include heavy glasses and pocket protectors. Strapping a calculator holster on your belt is going too far. If the earthquake of the day has occurred in Canada, the formula becomes somewhat more complex. AND if you are expected to show up immediately, a slight relaxation of the dress code is permissible. For example, jeans and tennis shoes would not be amiss, although you should try to make an effort from the waist up.
Sweatsuits are a tad too casual.
Miss Manners once commented that people clad in business suits at 3 o'clock in the morning are probably up to no good and should be regarded with suspicion. If interest in the earthquake continues for more than one day, on subsequent days you should revert to the more formal attire discussed previously. For those of you who will be sent to The Field, I have some additional advice. If you are expected to do some sort of science while you are There, you will be permitted to wear field clothing. If you want to know what proper field clothing consists of, I recommend that you watch Out of Africa .
