what is the dress code?

I mean, i wouldn't wear exercise clothing. That's about it. Also, don't believe the hype

The environment is casual but wear what makes you comfortable because there were a wide range of people dressing up and being casual

Casual

Casual is fine

I showed up in jeans and a sweater.

Casual to dressy. Must wear shoes. No tee shirts.

Yes it can be casual but people definitely dress up too.
