Prom has rules your school writes down, like the dress code and ticket deadlines. It also has rules nobody writes down. Who pays for what. When to show up. Whether to text through dinner. How to treat the people around you.
None of this is about being fancy. Good prom etiquette is just making the night easier for everyone else, so they make it easier for you. The Emily Post Institute even publishes a whole book on it for teens, Prom and Party Etiquette by Cindy Post Senning and Peggy Post. The short version follows, whether you are going as a couple, with a group or on your own.
Tickets and RSVPs
Buy your ticket before the deadline, not after. Schools plan food, seating and chaperones around those numbers, and late sales put real pressure on the volunteers organizing it.
If you are bringing a guest from another school, fill out the guest form early and make sure they know the school's rules. Some schools hold the student responsible for their guest. Our page on prom guest passes explains how that usually works.
Group plans count as RSVPs too. If your friends are booking a dinner reservation or splitting a ride, answer the group chat. "In" or "out" by the date they ask for is all it takes.
Flowers
Traditionally, dates exchange flowers. One person gives a corsage and the other gives a boutonniere. Today plenty of couples, friends and groups do it differently, or skip flowers entirely. The polite thing is simply to talk about it ahead of time so nobody shows up empty-handed while the other person brought something. Our page on who buys the corsage covers the options, and the prom corsage guide covers styles and ordering.
Splitting costs
Money is the place where unspoken expectations cause the most hurt feelings. The fix is to talk about it early and plainly.
Etiquette writer Julie Blais Comeau describes the traditional approach: the person who asks generally covers the tickets, the couple then discusses transportation, and each person pays for their own outfit, grooming and accessories. She also points out that parents often end up paying, so it helps to bring them into the conversation early. Many couples and friend groups now split everything evenly instead. Either approach is fine. What matters is that both people agree before anyone spends money.
In a group, pay your share promptly. If someone fronts the limo deposit, send them your part the same week. For the numbers, see our guides to what prom costs and who pays for prom.
Pickups and arriving
If you are picking someone up, go to the door. Do not text "here" from the driveway or honk. Comeau's advice is to get out, ring the bell and say hello to the family, and it holds up. Parents want to put a face to the name, and it takes two minutes.
Be on time, for the pickup, for photos and for the dance. If your group is meeting for pictures at a certain hour, late arrivals hold up everyone's schedule. Our prom day timeline helps you plan the hours so nobody is rushing.
At the dance
If you came with a date, check in with them through the night. Make sure they are having a good time, and do not disappear with your friends for two hours. That does not mean you cannot dance with anyone else. Dancing with your friends and your date's friends is normal, as long as your date is not left standing alone.
Be kind to the people who did not come with a date. Ask them to join your group dance. Include them in photos. Leave a seat at your table. It costs you nothing and it can change someone's whole night.
And be gracious to the staff. Comeau's list is simple: hello, please, thank you and you are welcome, for classmates, chaperones, school staff and the people serving food. The servers and DJ are working on one of their busiest nights of the year.
Phones and photos
Take your pictures, then put the phone away for a while. A dance floor full of people filming each other is not much of a dance.
Ask before you take someone's photo, and ask again before you post it. Comeau suggests a "two-fridge test" for anything you share, which roughly means asking yourself whether you would be happy to see the photo on your own family's fridge and on theirs. If someone asks you to take a photo down, take it down. Do not block other people's shots or hold up the line at the photo backdrop. For more, see our page on prom photos.
Leaving
Know how you are getting home before you arrive. If you came with a date or a group, leave with them or tell them clearly that you are leaving. Nobody should spend the last hour of prom looking for you.
Check your school's rules about leaving early, too. Some are strict. Kennedy High School in Fremont, California, for example, does not let anyone leave early unless a parent comes to the door with ID and speaks with an administrator. For the bigger picture on staying safe after the dance, see prom safety.
Saying thank you
Prom happens because a lot of people give up their time. Teachers chaperone on a Saturday night. Parents drive, pay, sew hems and stay up late. Students on the committee spend months planning.
Thank the chaperones on your way out. Thank your parents, out loud, the next day. Comeau goes one step further and suggests a handwritten note to the chair of the organizing committee, asking that it be shared with everyone who helped. An email works too. Either way, very few students do it, which is exactly why it gets remembered.
