Regal Princess, 2/23- Flow of Formal Nights

Hello, all! I've been combing Princess posts for WEEKS in preparation for our first cruise. So excited! Thank you for sharing your experiences, tips, and suggestions.

I'm still unsure about how "formal nights" work. I mean, I know folks dress up as much (or as little) as they'd like, but then what? Is it business as usual? With suits-n-ties and pearls-n-pumps in the buffet line? Or, is there a different vibe and structure to these evenings?

Thanks!
