I grew up in New Castle!!! I moved away after college. Augustine's Pizza is the absolute BEST, can't match it out here. Regarding how to dress, we dress for comfort...hadn't thought of the safety issue but we don't wear synthetics much anyway. I like to wear something loose b/c it is so cramped. I usually wear sandals but will wear tennis shoes after reading these posts. I flew non-rev on American last year and you do have to wear a dress or skirt, that's why you may see people dressed up some in the airports.
