Back to the non-rule rules: 1. If I wear a suit without a tie, I wear a patterned shirt. It looks less like I just forgot to put on a tie. Still, I do this as rarely as possible. 2. We are "business casual" at my office, but I wear a jacket or blazer or suit coat every day. No casual Fridays allowed. 3. I have casual cotton jackets that I wear in the summertime, but I don't pair them with nice wool trousers. Cotton goes with cotton. I have been known to wear a navy linen blazer with wool trousers, however. 4. I am not a purist on the whole "orphaned" jackets or trousers thing. 5. I go to as many black tie events as possible, and I always wear a self-tied bowtie. 6. I almost never wear shorts, jeans or T-shirts. I'll occasionally wear a polo shirt in a casual setting, but it can't have a logo on it. 7. If James Bond wouldn't wear it, neither would I. But just because James Bond does wear it doesn't mean I would. See "On Her Majesty's Secret Service" through "License to Kill." 8. I don't give a rat's ass about the clothing brand or even who made it, as long as it fits well, looks good, is comfortable and well-made. 9. I never, ever have an undershirt peeking out of my open collar. 10. Shirts get tucked in.
