Party Nails

Let's get this straight: we're not against mixing and matching nail colors...so long as it's done in a tasteful way. These "party nails" from Kaley Cuoco don't quite fit the bill. We get that she was trying to coordinate with her bright clutch, but when you mix such drastically different colors--especially at a formal event--it comes off looking a bit tacky. Come January, stick to colors in a similar palette for a chicer look.

Metallic Eyeshadow

Eyes, and lips, and nails, oh my! Metallics were everywhere this year and there's nothing we loved more than a sultry metallic eyeshadow. Consider it the smoky eye's sexier cousin, who's here to stay for 2012!

Super Saturated Lips

A good bold lip can do wonders for a look, but these super-saturated pouts are a bit melodramatic. Rachel McAdams' deep wine lipstick comes off as more Interview With The Vampire than we'd like for 2012.

You Can't Wear Lipstick Without Lip Liner

Whoever said you can't rock lipstick without a lip liner was probably the type of kid who couldn't color in between the lines. These days, lipsticks can hang all on their own, without any help--check out Elizabeth Olsen's liner-free lips for proof. Just make sure you have the proper tools, to prevent your color from running. "Invest in a quality lip brush that glides color on and keeps its shape," says Stila Pro Artist Sarah Lucero. "Use it like a flat paint brush and start the application by loading color on the center lower lip and then pull out and perfect it at lip line from there."

You Can't Wear a Smoky Eye And A Bold Lip

The secret to pulling off Taylor Swift's fierce smoky eye and bold lips? Keep the rest of your makeup sheer and focus on your skin. "Wear a tinted moisturizer and skip powder if you can," Lucero says. "Complexion needs to be a bit dewy and very touchable, so less is more."
