Q: Say you're wearing black shoes, blue jeans, and a white (or similarly neutral) button-up shirt. What belt are you wearing? Is it black? Does it have to be?
A: West, please refer to our super-scientific black shoe dressiness and belt blackness chart.
If you're at Point A, with something heeled and hard-soled that needs polishing, belt blackness requirements are high. (Also at Point A, with the outfit you described, you are in the Blazer Zone. See our blazer channel for tons of tips.)
As you move down the y-axis into sneakerized dress shoes (Point B), belt blackness drops precipitously. If we were wearing the Prada Spazzolato Leather Penny Loafers shown above, we'd feel completely comfortable in our 300-Year Sterling Silver High Plains Noir belt, which is MB longhand for "very dark brown."
Finally, further down the scale into sneakers (Point C), the belt blackness spec is loosened almost completely, sort of like traveling in the NBA. Here we'd be in a sport belt (like our own SAB) and, yes, even brown.
Next time you put on black shoes, apply the chart, and let us know what you think.
