Ohhh! How would you describe the shade of grey? Charcoal, lighter than that, darker? Is it definitely grey, or is it so dark of a grey that from a few feet away, it could pass for black patent? Trying to get an idea!
I tried on the grey GST as well, and it was a very light grey, with a lavender sort of hue. Lighter than charcoal for sure. It's pretty and the SA told me it could be a 4 season bag because it's a very neutral grey. I would have preferred a darker grey though. Also, the leather is the washed caviar so it has a smoother texture than the regular caviar. Not sure if I like it so much.
Here's a pic of the grey GST. I haven't seen it IRL either, but I think it's very pretty in the pic.
