I`m going to go to a wine party tonight!

I am invited to the wine party tonight.
This is not so fomal. This is a party to enjoy the conversation drinking wine,so I don`t have to wear a fomal dress.

I`m invited by the conversation organizers who is more than 30years
older than me.
He has asked to some member about today`s party,but he receibed
the OK from only me. The other people might be inconvenient because of weekdays.

Anyway, I don`t have a chance so much to go to such a wine party.
I`ll enjoy drinking and conversation with unknown people.
(I don`t have a knowledge about a wine anything.)
