Belt with formal outfit?

[M. A. C. Newsome]

Thanks for pointing that out, Matt.

I guess the other side of that is that a belt should always be worn when not wearing a waistcoat or cummerbund.

Hmmm... I don't know if I'd say that as a rule, necessarily. As this thread is about formal wear, one could say you were correct. For formal attire, unless you are wearing a vest or a cummerbund, I'd wear a belt.

However, I don't think that statement is true for casual wear. There are all kinds of circumstances in casual wear where you might not wear a belt. For what it's worth, I'd rather see no belt with casual wear than a dress belt worn with casual wear.
