Old School Etiquette

Etiquette Rules from an 1888 Etiquette Guide

      

You should dress quietly at your own entertainment's, thus avoiding the possibility of eclipsing your guests.
You should speak without arrogance to those serving you. They may be as well born as yourself.

 

You should strive to live down all false and evil reports, but never to contradict them.

If you have been sick yourself, say as little about it as possible, and never allude to it at the table, where you will receive little sympathy and perhaps render yourself offensive to all who hear you.
You should shun boasting. It is vulgar.

 

You should reject dresses that are too low necked and those that have almost every vestige of sleeve cut away.

You should, if old, show consideration for the faults and follies of the young. If young yourself, be gentle and respectful to those of riper years.

You should never take dogs with you, nor pets, unless they are specially invited.

You should never bang doors, especially entrance doors.

To laugh heartily, or to whisper unfavorable remarks during the performance of a concert or a play is a rudeness of which no gentlewoman would be guilty.

 

And my personal favorite... Which shows how much fashions and etiquette have changed since the Victorian age...
Be careful not to
Show your ankles,
However pretty they are.
