Prom rentals are a popular service for special occasions such as proms and weddings. The term PROM RENTALS can be broken down into three solutions: TUXEDOS (7 letters), LIMOS (5 letters), and TUXES (5 letters). Tuxedos are formal suits typically worn by men to formal events. Limos are luxury vehicles often used for transportation to and from special events. Tuxes are the same as tuxedos, but is a more informal term.
