Etiquette

[twoheaded_boy]

While volunteering as a functionary at a high-priced ($250/ticket) gala, is it permissible to:

- pretend that high-quality black jeans are actually dress pants?

- wear a blue pinstripe shirt instead of a white shirt?

- wear a black tie with a blue shirt?

- not wear a blazer?

- roll up my sleeves?

Please help me gauge the severity of these gaffes and determine how many I'm allowed to make.
