Boxing is a martial art where two participants, generally of similar weight, fight each other with their fists. Boxing is supervised by a referee and is typically engaged in during a series of one to three-minute intervals called rounds. There are three ways to win. Victory is achieved if the opponent is knocked out and unable to get up before the referee counts to ten seconds (a Knockout, or KO) or if the opponent is deemed too injured to continue (a Technical Knockout, or TKO). If there is no stoppage of the fight before an agreed number of rounds, a winner is determined either by the referee’s decision or by judges’ scorecards..A ring girl is the common name for a woman who enters the ring between rounds of a combat sport event such as boxing, kickboxing, or mixed martial arts, carrying a sign that displays the number of the upcoming round.Ring girls almost always wear a swimsuit or bikini and high heels; however, some ring girls wear evening gowns. In some female boxing matches, ring girls are replaced by ring men dressed in tuxedos.
