I'm going to attend an aviation tradeshow that and airline I'd like to work for will be at. I've been to the tradeshow before and it's very informal with lots of GA related presentations and booths and very few people formally dressed. Being that I'm going to try to meet HR and give them a resume, what would be a good dresscode? I want them to think I'm serious and I care, but not that I'm VERY overdressed for the event or a dork for showing up in a suit if that makes sense... But I'm happy to do so if that's best. Thoughts?
