Well, if I'm honest I just wore a piece of rectangular fabric my mum had sown into a dress and my hockey socks.
Well if I'm really honest I was the fat, ginger kid with ridiculous amounts of hair. I was practically Molly Weasley but with less offspring.
Everyone was in awe of my costume and I made heaps of friends. We would sit and talk about Harry Potter for ages. We would discuss what might happen in the fourth book, we played pretend games where we got sent to hogwarts. We were, in short, totally awesome.
