How radiant is Rachel Weisz at Monday's premiere of "The Lovely Bones"? Those eyes, that lip—
she looks absolutely flawless.

Below, CHANEL Celebrity Makeup Artist Kara Yoshimoto Bua shares how to recreate the actress's latest look:

On the Lips
I was inspired by the color of Rachel's dress, which was calling out for a perfectly red lip! I chose the semi-matte CHANEL Rouge Allure Laque in Dragon. I love this shade because it is a very pigmented blue true red, perfect with Rachel's fair skin, and can be worn very sheer yet give vivid color.

For the Eyes
I wanted shimmery soft eyes to be tonal with the color of the dress so as not to compete with the lips. CHANEL Quadra Eye Shadow in Murano has the most beautiful greenish-gray shimmers that accent Rachel's dark hair and brown eyes. CHANEL Inimitable Mascara in Noir-Black opens up her eyes by lengthening and separating her already thick lashes without any clumps!

On the Face
CHANEL Blush Duo Tweed Effect in Tweed Rose gives her a soft tint of color in the apples of her cheeks.

Have wavy or curly hair? If so, I've got one simple question: are you a mousse or gel kind of girl?

If you're anything like me, your answer is probably based more on habit than hair type. The better question is: which should you be?

While both mousse and gel can provide top results, it's important to understand which product is best for your tresses. The first thing to consider is the look you're trying to achieve. Traditionally, mousse is used for volume and and gel for sculpting.

Once you've decided on the style, consider your hair type. If you have fine hair but crave definition as well as a lift, try a strong hold mousse. If your locks are a bit unruly and you'd like a softer look, opt for a lightweight gel or gel-creme.

Finally, be sure to read the directions on a product carefully and follow the instructions as they're listed. You may find yourself a fan of a former foe once you've had a chance to see just what it can do.

Have any gel/mousse tips of your own? Do share!
