Denim shirt over evening dress?

[AWimbaWay]

I'm going to a summer ball later, it will be in a marquee so thinking I'll need some kind of cover up in case it's a bit chilly. I don't really fancy a cardigan, jacket or shawl but was thinking of a denim shirt like this:

Would it be too odd and dressed down?

Honestly? I think it would ruin whatever you are wearing.

I think it would look bizarre. Sorry

I thought that might be the verdict

It's a choice between these two dresses, any ideas what I could wear over?

I think the second one would look great with a denim jacket! Its kind of rock chick. The first one requires a sweet waist length cardigan or a pashmina.
