A good party is one that is designed to entertain and bond friends. The bad parties I've been to are the ones that are held to impress other people.

Often times I'll quickly dash off an email or text message when I leave a party. A particularly enjoyable evening, however, that warrants a thank-you note or a phone call. I always say a handwritten note is the ultimate hallmark of a classy woman. But an email is better than nothing.

I think the sort of person you want at a party is someone who is self-aware, polite and has a basic knowledge of table manners. And that goes for both men and women.

Getting last-minute cancellations can put a black cloud over an event before it has even started. If it's a large, casual cocktail party, then I'll often not say anything until the next day. But if you're not able to make it to a small, seated dinner, you have to call the host - there's nothing worse than an empty chair at a table.

Talking, texting or tweeting on your phone is the worst in any social situation. I went to a lunch during Paris Fashion Week, and I managed to steal a few moments with Lee Radziwill - who I think is perhaps the classiest woman alive - and she said this is her biggest pet peeve too. So I'm in good company.

I grew up in the Midwest, so I have sort of an honorable moral code. But I moved to a city and joined a sort of fast crowd. A lot of people who grew up in the city sort of arent aware of manners and other ways of life and common decency.
