10 New Style Rules

From colored lace to thicker brows -- try out a new set of fashion and beauty ideas for fall.

A dark part used to mean you missed a salon visit. But imperfection can be cool, provided roots are only a few shades away from your highlights.

2. Go Short for Black Tie
Yes, you can wear an LBD in a formal setting, but choose one with a beautiful detail such as a giant satin bow or a graceful tulip hem.

3. Stay in Sandals
No need to retire them yet. Strappy footwear looks great for fall with dark stockings (as do peep-toe pumps).

4. Grow Out Your Hair at 40
Buck the trend to trim your tresses. But condition so your locks are as lush. We like Pantene Pro-V Beautiful Lengths conditioner, $4; at drugstores.

5. Go Sleeveless
It's time to rethink the jacket for fall -- 3.1 Phillip Lim, Diane von Furstenberg and Calvin Klein all showed sleeveless ones as a bold new option.

6. Don't Match Your Stockings to Your Shoes
Last year: matching tights and ankle boots. This season: different hues for your heels, tights and -- per Proenza Schouler -- your gem-tone shift.

7. Pick a Print That Makes You Look Slimmer
Especially if it comes in the form of a flirty little camisole with strategically placed panels to streamline your figure.

8. Step Out in Colorful Lace
Fashion insiders normally find it tacky, but on the fall runways of Prada and Jean Paul Gaultier, the styles looked chic in orange, teal and chocolate hues.

9. Mix Your Metals
That old adage of wearing only silver or gold is gone: An armful of bangles in both -- the shinier the ores the better -- suddenly feels right.

10. Fret No More About Hemlines
Mom always said a coat should hit right at a dress's hem, but for once she's wrong. Designers have been flouting the rule with renewed vigor this season -- and you should too.
