Dress nice it's always a nice crowd
We were dressed up. But did notice a few in slightly casual. Definitely not shorts and tennis shoes. But jeans and a dressy shirt for a guy would be ok.
I'd say it's casual, but a little more on the preppy side. You'll be fine with jeans but I would wear shoes & not sneakers.
There was no dress code as far as I understood. I had tshirt on and I was ok. But the majority was wearing suits and such though.
