I know you shouldn’t… but I did. I applied nail varnish right before going out. But I didn’t apply a thin veneer, I applied a big thick blob and then preceeded to spread it all over myself and around the flat.
However if you decide to do this, ideally you should have a friend who can put a small amount on that will dry quickly, and will be willing to help you hold bags and keys with out smearing nail colour everywhere.
But I had a good night despite the dodgey nailvarnish on my left hand.
