It doesn't take long for freshers to adopt the Oxford way of life — working and playing hard, and feeling equally comfortable in black tie, subfusc (formal academic dress) or fancy dress.
In Britain, people carve scary faces into pumpkins and children go trick-or-treating, dressing up in fancy dress costumes and visiting people's homes shouting, " trick or treat! " for sweets and candy.
And now that is expensive, but if you don't want to spend 2,000 US dollars on a really fancy formal dress, this is a really good way to save money and also think more green.
