There are a couple reasons to buy and wear one of our cheerleader costumes for Halloween. All of them are good choices. If you are athletic and fit, then you will look great in a sexy cheerleader uniform. If you want an excuse to chant at the top of your lungs for an evening and relive your high school or college cheerleading days, then one of these schoolgirl costumes will work well. And if your boyfriend wants to go in a sports outfit and you want to match him, cheerleader costumes make the perfect finish to the couples costume.
