The way we dress can determine how others perceive us. According to the April 1995 issue of "Basic and Applied Social Psychology," our physical appearance can impact our social experiences, can reflect our cultural preferences and may have an effect on our likability among a group. Reunions are formal occasions, even if they are being hosted in casual environments. Whether your reunion is being thrown at The Bellagio, or a bar, it is good etiquette to dress up for the festivity. Dressing up not only is nice on the eyes, but it also shows a level of respect for the formal occasion.
With a room full of people who haven't seen each other in many years, a considerable amount of chatter can be expected. To be polite, engage your old classmates in conversations and participate in the dialogue by sharing your experiences as well. If classmates bring their spouses, significant others or children, be sensitive about the material you discuss in your conversation. Bringing up old stories about your classmate's high school sweetheart in front of their spouse, for instance, may not be in good form.
Even though class reunions are supposed to be fun, it doesn't give you permission to check your manners at the door. According to the September 2005 issue of "British Journal of Educational Studies," minding your manners is a virtue that will impress those around you, no matter the place or occasion. As such, treat your class reunion the way you would treat a work seminar or function. Be respectful of others, practice good listening skills when others are talking and abide by the standard tableside manners.
Grownups are just as susceptible to forming clicks as kids are. Since you are about to rejoin your old friends from school, it is possible that the same old groups will form around the room. To practice good reunion etiquette, try and avoid the clicks by circulating around the room and interacting with everyone equally.
You may not like every single person at your class reunion, but it is important to maintain a positive attitude. Put the past behind you, and be friendly.
