There is no strict rule that your shoes and belt must match, but it is generally considered a good style guideline to do so.
Matching your shoes and belt can pull together your outfit and create a more polished look. However, it is not essential to have an exact match in color or material. Instead, aim for a harmonious pairing that complements your clothing. For example, a brown leather belt may look great with dark brown shoes but can also work with a lighter shade of brown or other earthy tones.
Ultimately, it is up to personal preference and the occasion you are dressing for.
In casual settings, you can opt for a more relaxed approach, while in more formal settings, it’s best to make sure your shoes and belt match to project a put-together look.
