Hi, Paul !
In my country we usually wear a jeans and hoodies but you can wear something else if you want to. At official parties, guys can wear-trousers and a white shirt. And if you have something to wear, you can go to a clothing store and buy yourself something there. If I were you, I wouldn't worry about what to do, the main thing is that you like it, don't worry!
Bye, Paul.
