I have my ASP coming up end of this month. Curious as to what sort of attire people wore; I am guessing a suit or business casual, yet during the full day sessions its a PT attire underneath a flight suit, correct? Which would mean wear the suit/business attire/smart casual en route there, and after hours (dinners etc) when you won't be in the flight suit? Silly question I know, the letter didn't explain in great detail as to what sort of attire is expected that's all.
