I actually find the ring Victoria is wearing to add some life into an otherwise traditional look. It is an eye catcher, yet doesn't take away from the classy dress.
As for her hair, it was kinda risky do wear something slightly messy looking, but she pulls it off.
Dannii looks very put together. Victoria looks more modern.
This dress has the potential to be quite boring to look at. With Victoria, I feel she has added just the right amount of pazazz.
