Knowing that, most celebrities hire stylists to glam up their hair, makeup and wardrobe for these events.

But they will only look as good as two factors: One, their own level of taste; the other, their own choice in stylists.

That’s why Penelope Cruz, Chloe Sevigny, Nicole Kidman and Reese Witherspoon are sure bets to always look amazing. They’re not only talented in their craft, but they also make the most of their physical features and attributes.

Penelope is curvy and small; Reese is very petite; Nicole is tall and a breeze to look great; and Chloe has a gorgeous figure and legs. All these ladies have great hair and know how to show it off. They don’t allow the latest “messy” or “dirty” look to become their own. They understand the perfect marriage of what’s classic, modern and yet imaginative so that we never tire of following their style cues. They also understand the power of color, and when they do wear black, they make it interesting and high-style.

All four celebs don’t fall prey to overexposure. “Cuteness” is not in their vocabulary. They don’t confuse “glitzy” and “over the top” for “glamour.” And trying to look too young or frozen in time will, hopefully, not be a pitfall they’ll fall into.

They definitely get my style awards!

What you didn't see almost without exception on those beautiful and famous chests and necks was bling. Rarely do actresses rely on what nature gave them from the bust up to look good. But some didn't pull it off, with hair that looked like they were on the way to the hairdresser.

Sandra Bullock got it right with hair put up with several wavy tendrils softly hanging down. And Christina Applegate -- hair up, strapless gown -- looked stunning. The key to all this? Neck length.

If you have a short neck, definitely wear your hair up: It will lengthen your strapless-gown look. For a normal-length neck, you have the choice, up or down. As for a longer neck, up is fine, but some tendrils will make you look less severe. Over-one-shoulder hair (Penelope Cruz and Mariah Carey at the SAGs) is very elegant with a one-strap gown.

Try these styles, and you’ll soon look like your favorite star.

Admit it. We've all seen her (or been her) at one time or another, the girl

whose eye shadow is dazzling, lip color gorgeous, blush to die for … and foundation the color of another person’s skin entirely!

She obviously took time to make the rest of her face look great, but her foundation doesn’t complement her at all.

A lot of women drop the ball when it comes to their base. They don’t follow the “Foundation Rules”, which begin with, “Your foundation shall be your exact skin tone and texture at all times. Not the color you want to be, not the color you were in the summer, but the color and texture of your skin when you woke up that morning.”

Not all foundation is created equal. You want to find the texture that will complement your skin and counteract any imperfections. To choose the texture that’s right for you, take your skin type into account. If you have oily skin, skip creams and luminous formulas, or your face will look like a bedazzled disco ball. Try an oil-absorbing powder type instead. For dry skin, avoid powders and matte formulas. They will age your face by settling in fine lines.

Now on to the right color! I always advise my clients to have two foundations: a match for winter and a slightly darker shade for summer. Test your foundation on your jawline and blend up to your cheekbone. Your color match should be spot on and undetectable.

Like all makeup, foundation should enhance your complexion and correct your flaws. Simply follow the Foundation Rules for a beautiful complexion!

An old wives’ tale says that eating bread crusts is a surefire way of making your hair grow curly. Have you tried it? Unfortunately, it’s much more complicated than that. In fact, a number of different theories still cloud around the formation of curly or wavy hair, and the truth may lie in a combination of factors.

When you look at hair under a microscope at high magnification, it’s clear that there is a very visible difference between hair types. For example, Asian hair, which is almost always straight, has a regular circular cross-section, whereas hair of African descent, which is almost always curly, has an oval, kidney shape.

So the cross-sectional shape of the hair fiber seems to play a key role, but what actually determines the shape of the hair in the first place?

To understand this, we need to look at the way in which the hair forms within the follicle from its individual cellular building blocks. Some evidence leads scientists to believe that differences in the protein composition of the cells within the hair could be the fundamental cause of differences in curl.

Whatever the cause, like most of the properties of your hair, there is certainly some sort of genetic component. So if you don’t like your curly locks or wish your hair wasn’t so straight … then blame your parents!
