Here's my plug for the Mini Classique style. It's fabulous for going out and actually stays on the shoulder even when dancing and I move my shoulders a lot when I dance, but the strap is small and the whole bag is well balanced.
You wouldn't know you were wearing it except for all the compliments ;o) and it's small enough that it doesn't get in the way when there's a crowd.
You should definitely get one! Maybe in one of the colored metallics like magenta, red, orange or pink. You have all the metal colored metallics covered, Deco-girl!
