(InStyle.com ) -- Here are ways to stand out from the crowd this season by shaking up the style rules.
Vibrant red shadow gives eyes a bold look.
Rule 1: Emphasize eyes or lips, but not both
How to break it: Pair dark eyes with dark lips -- just stay in the same color family. Try deep plums and eggplants on eyes (plus black liner) and a sheer dark red or plum on lips.
Yes, it's all about the '80s. "Channel Xanadu and have fun," says makeup artist Natalie Miller.
Rule 2: Glittery jewelry is meant for the evening
How to break it: Don't treat your fancy stuff like a vampire: Let it shine in the daylight! To make it work, keep the rest of your outfit subdued and sophisticated -- understated, clean lines will let your attention-grabbing jewelry rightly hog the focus.
"I love a big statement necklace over a plain, basic T-shirt," says stylist Elizabeth Stewart. "Worn with jeans and a cardigan or a boyfriend jacket, it looks fabulous." InStyle: Summer work style rules
Rule 3: Mixing patterns or clashing colors is a no-no
How to break it: Somewhere between good-girl boring and worrisome wacky is the fun zone. Why not combine two or three unusual choices like a lilac-and-taupe checked sweater with a chartreuse skirt, says designer Rachel Comey. In general, keep colors within the same tonal family and don't mix patterns that have more than two colors.
Rule 4: Chipped polish must be removed immediately
How to break it: You can tough it out a few days after your manicure starts to fray, says nail expert Ji Baek. Just use a matching color to stroke a light line sideways across the worn area, then paint the entire nail with a top coat to blend.
Rule 5: No bangs on round faces
How to break it: We're not pushing the Little Dutch Boy look. But the right cut will soften the bluntness. Have your bangs trimmed in a subtle arc so the sides are longer and more fringey, recommends hairstylist Léa Journo. "It'll help bring out your bone structure," she says.
Rule 6: Light scents for day, headier scents at night
How to break it: Robert Gerstner of Aedes de Venustas says to forget complex vs. simple, night vs. day, even men's vs. women's: "Spray on a scent with traditionally masculine elements like the leather and incense found in Aedes de Venustas; wear something heady and dramatic like Fracas in the daytime; pair an unexpectedly simple floral with an over-the-top outfit."
Rule 7: Always enhance your natural lip color
How to break it: Bring on the beige, says makeup artist Pat McGrath. This season, models hit the runways with superpale nude lips. Layer concealer and lip balm to achieve a hue that's the same color or slightly lighter than your skin tone. And pair with glowy skin or dark eye makeup to avoid looking washed out.
Rule 8: You can't wear denim on denim
How to break it: Sidestep a Texas tuxedo look with a chic tweak: Pair contrasting denims, like dark indigo jeans with a pale chambray shirt. Keep it sophisticated, not country or kitschy. Finish the look with a strappy shoe and studded bag.
Rule 9: Take off one accessory before leaving the house
How to break it: These days, more is more. "Put on all your favorite things at once," insists jewelry designer Philip Crangi.
"Accessories are the way people tell their stories. I love the mix of new and old, high and low, glam and personal. Pile it all together: a Cartier Love bracelet, a piece of string, a Swatch, beads, cuffs and bangles -- you should always feel more like you in your outfits." InStyle: 10 bargain finds from the pros
Rule 10: Red is only for lips and nails
How to break it: At the Prada and Gucci shows, vibrant red shadow gave eyes a bold look. Build up the color gradually, says Pat McGrath. Make it most saturated at the base of the lashes. Wear with smoky black pencil and black mascara on the top and bottom lashes. On lips, opt for a deep, cool red or a nude shade to give the edgy eyes the focus. InStyle: Get great skin at any age
Rule 11: Short haircuts aren't suited to curly hair
How to break it: Just don't go crazy with layering. Too many short layers make hair spring up, creating an unflattering pouf, says Frédéric Fekkai hairstylist Adir Abergel. "The key is to cut longer layers, which keeps the weight at the bottom of hair," he says.
Rule 12: If wearing color, nails should be short
How to break it: "An almond-oval shape is more current and lengthens the hand," says manicurist Roxanne Valinoti. Angle your file at 45 degrees just under the tip so you keep the length on top and sides.
Rule 13: Wear open-toe shoes only in the summer
How to break it: Tights are going to be huge for fall, and they look great with sandals. "Stick with thicker-strapped pairs that don't expose too much of the foot -- they'll also keep feet from sliding around," says our accessories director Meggan Crum. "And wear with opaque tights in autumn colors like burgundy or dark mustard, or classic black."
