What would you wear to a party that is for hockey (details under)?

So I got invited to a party but it is like a hockey party and to watch the hockey game. It is the Toronto leafs game and ik the obvious wear a jersey but...

1- I don't own any hockey jersey

2- I don't want to buy any hockey stuff because I won't use it after hockey is done

3- It doesn't look sexy or cute and I think things might get intimate and doing stuff in hockey clothes is not what I want to experience ๐Ÿ˜‚
