Rule #1
Don't wear your hair longer than to your collarbone.

Rule #2
No red lipstick, unless you have dark or olive skin. It's aging.

Rule #3
No blue jeans to dinner out. (But black jeans are okay.)

Rule #4
Don't expose your knees. And cover up. Don't try to compete with 20-year-olds. A woman between 40 and forever looks great because she has style, not because she shows off her body.

Rule #5
Don't ever wear anything strapless.

Rule #6
But at the beach, if you have a toned body, rock that bikini for as long as you like.

Rule #7
No miniskirts. A short skirt is okay with black tights.

Rule #8
Don't ever revisit a trend you lived through once before.

Rule #9
Don't wear hats, except to keep the sun off your face. A hat makes you look as if you're trying to get noticed.

Rule #10
Wear fewer accessories, and keep your look clean.
