What is appropriate baby wedding attire?

DC1 has his first wedding next week. He’s 6mo. Can I get away with his special Duns dungarees with oranges on, or should I get him one of those little rompers that look like fake suits? I was thinking maybe this one from M&S:

as an aside definitely not this one from Next, the poor baby looks so uncomfortable!

My DD one was eight months at my sister's wedding and she just wore some cute dungarees with Peter Rabbit on.

A fake suit sounds uncomfy and a bit silly for such a young baby!
