Investor Group Meetups

[Trace Carson]

Hello everyone, I have joined (online) investor groups in my area, which is Boise, Idaho. I am going to try and go to some of their meet ups whenever work permits the time. 

I am simply wondering what is common etiquette and dress at most meetups such as these? And as a total newbie and only 20 years old, will I be completely out of my league? 

Thanks everyone
