The Etiquette

Basic do’s and don’ts of party planning

Modern-day party-planning etiquette can be tricky, particularly for the hostess. It feels like the general rules are always changing and usually subjective, so I’ve compiled my tried-and-true tips for hosting an event with grace and consideration.

I try to send out invitations four weeks in advance. People’s calendars fill up quickly, but sending the invitations too early risks them being misplaced or forgotten about. Obviously, for weddings and larger-scale events that may require travel, you should afford your guests additional time, while two weeks’ notice is enough time for a smaller, more casual gathering.

Make certain to properly greet and introduce partygoers, even if you believe they may have already met. Social gatherings can be intimidating, so do your best to make each guest feel comfortable. (Take a note from Bridget Jones and try to offer an interesting fact about each person to help spark a conversation!)

Avoid serving fussy or antisocial foods. Keep the menu simple and familiar. Do not serve heavily garlic- or onion-infused dishes. Socializing with stinky breath is not good for anyone involved.

Invite guests with a date, if the budget allows. It makes for a better time for everyone. If the budget is tight, be very clear in your invitation so that you don’t find yourself scurrying to set an extra place setting when the guest arrives with a plus-one.

Don’t invite a second-tier guest list too close to the event. People will know they were not your first choice, and no one wants to feel like the second-string.

Be prepared. Give guests as much information as possible ahead of time regarding parking, transportation and attire; have a backup plan in case of inclement weather, etc. The more you anticipate and do ahead of time, the better your event will be. There are always inevitable hiccups on the day of, so it’s best to eliminate or minimize the foreseeable bumps so you have more time to focus on the unforeseeable ones.
