Teenage party dresses can be worn for attending weddings, celebrating with friends or enjoying your own birthday party in style. They also suit events such as Homecoming or a Quinceañera. For black tie events for teens like a debutante ball or cotillion, a formal junior dress fits the dress code best. These pretty gowns can include bows, short sleeves, embellishments or cute halter necklines. A long formal gown for juniors can also be worn for junior miss pageants, prom night or other dressy events.
