I didn't get into dressing up or anything that vaguely resembled cosplay until around the seventh grade, when I got an inflatable cow costume to wear on Halloween. I loved it so much that I just started lounging around in it when no one else was around to see me in it. There's nothing immoral about it, but my parents did get a little upset when I suddenly started to buy occasional masks and costumes a few years back without any clear explanation why. I don't have a huge collection, mind you, but I did get ones of my favorite animals.
