The rule that your belt and shoes need to be the same color is old school, feel free to change it up.
Tip #14 Exposed:
I used to make myself crazy trying to get my shoes and belts to be exactly the same color. To the extent that I would take my shoes to the store when shopping for a belt. While many may still think they need to be the same color, this is not the case anymore (for sure). However, I do advise the colors match. Like in the above image, light brown and black do work, but I would stay away from dark brown and black. White belts go with every color so if you like colorful shoes and want a universal belt feel free to go with white. The days of making ourselves crazy for the exact color match are over!
