I vote for anything swift or box for a transition to night. Nothing bigger than a 30cm..DEFINITELY GH! As far as color is concerned, I think your evening wear will dictate what color you need to get. If you wear a lot of light colored ensembles, then a biscuit would be lovely. If you wear mostly darks, go for the marron fonce or simple black, but not a textured black. I love love love GH...I think it suits for bfast, lunch and dinner!
