Chair covers.. worth it or not?

We had them, because the chairs at our venue were not only ugly and banged up, but mismatched. (There were some banquet chairs, and some metal folding chairs.) And we bought them before the wedding, and resold them afterward, so the cost was minimal. Under most circumstances, I'd consider them unnecessary.

I will be getting chair covers. Personally it just completes the wedding look that I have in my head. Renting them can sometimes be more expensive than buying them off ebay
