Hi, Carl and Emmy ...
We've not cruised on Crystal, but have sailed "upscale" a few times.
For the most part, we've found the people to be "just folks". We certainly are.
As an insight, I was chatting away with a fellow and his wife somewhere on a mountain in Costa Rica ... we were mostly discussing camera lenses. I don't recall how the talk turned, but the upshot was every piece of clothing on my body came from a department store HE owned (along with about two dozen other department stores). He and his wife were -- still are -- we stay in touch -- "just folks." As in just folks with a gazillion dollars.
My experience has been (this is for Emmy, in particular) that the more upscale the ship the more scaled-back the ladies' wardrobes are. You see a lot of the "LBD" (Little Black Dress) with pearls.
I guess the deal is that the more you have, the less you need to show it off.
So, have a wonderful time. I've never heard anything but praise for the Crystal product.
