Prom (short for promenade) is a formal high school social event—most often a dinner dance in the spring—where students dress up, take photos, and celebrate the school year. It is a bigger deal than a typical school dance: think suits, tuxes, and formal dresses, plus sometimes pre-prom (“promenade”) and after-parties (which are not school-sponsored by default).
What usually happens
- A theme (decoration and sometimes dress inspiration).
- An evening schedule: photos, dinner, dancing, and sometimes crowning a prom court.
- Chaperones and school rules about behavior, curfew on school grounds, and substance policies that still apply.
Who goes
Traditionally juniors and/or seniors host or attend, depending on the school. Some schools allow guests from other schools with a form and ID. Check your student handbook for the exact rule.
Dress code in plain language
Guys usually wear a suit or tuxedo, dress shoes, and sometimes a bow tie or long tie. Girls often wear long formal gowns; schools may publish hem length, strap, or modesty requirements. The goal is a formal, cohesive look, not a club or gym outfit.
What prom is not
It is not a requirement for graduation, and the “movie version” of prom (limos, after-parties) is optional. The core idea is a ritual with your class in clothes that mark the night as special.
Takeaway
What is prom? A formal spring school dance with a dressier standard than other dances, organized by the school, with clear rules and dates published by your class or administration.
