I prefer silver hardware most of the times and especially with black. It looks much more casual. I'm really happy that I picked the silver because it looks great with the crash leather but if you prefer gold I'm sure the bag is stunning, too.
I LOVE silver..i almost never buy bags with gold hardware..silver just goes with more of my jewelry, clothes, lifestyle, and doesnt change color as much as gold toned hardware. Overall, I just tend to use and enjoy my silver hardware bags way more than my gold hardware ones.
