Looking at a variety of briefcases for myself and it appears I have the choice of brass or silver hardware. So I'm looking at black leather with either brass or silver (for a surcharge) buckles. This will also be my first briefcase, which is exciting. Does anyone have any thoughts? I'm leaning towards silver because, generally, I only wear white metals and avoid gold, however I'm worried about corrosion. Is there any reason to prefer brass over silver? Apart from cost of course? Brass seems to be pretty standard, even on black cases ... And silly question, but if I were to go with brass, is that cool considering I tend to wear navy suits mostly and white metals?
