FIVE MODERN ETIQUETTE RULES TO KNOW.

Florida-born Myka Meier, the princess of Ps and Qs, or, if you will, the Marie Kondo of etiquette, shares her guidance on how to display perfect propriety. The founder of Beaumark Etiquette and author of Etiquette in Society, in Business, in Politics, and at Home, has trained everyone from global titans of business and anxious brides-to-be, foreign princesses, politicians and celebrities (not to mention the entitled offspring of celebrities and their nannies). One of her early courses was titled Marry Harry, designed to snag the then-single prince. Meier has these quick tips for the rest of us:

1 CALLING CARD

Keep your mobile phone off the table, always. If you’re expecting an important call, keep it on your chair, beside your leg, screen up, on silent. When it vibrates, excuse yourself and leave the table to answer.

2 BOUQUET BARB

Don’t take wine or flowers to a dinner party — your host will have to find a vase for flowers and miss greeting guests. Or have them sent to arrive the morning of the event. Wine may not pair well with the menu, or it may signal to your host that their taste isn’t up to standard.

3 EYES LEFT

At a party where you don’t know anybody, practise Wolf Pack Socializing. Every wolf pack has an alpha, a beta and a fetcher — identify the animals, then approach the fetcher, who will be the most open. Left eye contact is the most important if you want to come across as likable. If you want to come across as authoritative, look directly into a person’s right eye. Avoid gossip, and don’t talk about sex, politics, money or religion.

4 DIAMONDS ARE FOR DINNER

Large diamonds should only ever be worn after 6 p.m. Other than marital jewelry, only gold, silver and platinum jewelry or pearls and gemstones are appropriate for

daytime.

5 PERFECT TIMING

Always arrive 10 minutes afterthe stated time the dinner party will begin, and leave no more than 30 minutes after dessert.
