There are few holidays a collegiette loves more than Halloween. You may be too old for the days of trick-or-treating, but the new treat has become deciding what you’re going to dress up as each year. Once October rolls around, you start brainstorming ideas for your costumes. Halloween used to last for just one night, but in college, Halloween becomes a weekend-long event, which means several different costumes. You and your friends might plan some group costume you can all dress up as together… …or you might find it easier to just come up with some solo costumes.
