i dont quite know. nobody i have spoken to have mentioned taking one, nobody on here has suggested one. maybe i have been oblivious to the fact that we may have a freshers ball? (i dont think we do?!) and as for the 'wine and cheese evening' i dont think people are dressing up ridiculously smart for that, for those that are going its more of a social event than a formal affair...
i dont own a suit, i wont be taking a suit, i havent been told to take one by anybody, nobody has mentioned it, so thats my take on the topic at hand, maybe other people have heard differently?!
