Advice for first hoco?

Hey, freshman here👋 My hoco is coming soon and I was wondering if anyone had any advice? That’s very vague but I just don’t know what to expect. I’ve been to middle school dances, but the ones at my old school were pretty lame ( it was a small school ). I go to a huge high school now, it’s a Catholic school but it still functions like any other school except they teach religion. The kids are no different.

What stuff should I bring? What should I wear? What should I expect? Any advice would be much appreciated💖
