Despite rocking a racy, black leather mini at the Horrible Bosses photo call in London early Wednesday, Jennifer Aniston opted for a more demure look at the comedic flick's UK premiere that evening.

Clad in a sparkling knee-length cocktail dress by Valentino, the 42-year-old actress looked ever-ageless with flawless skin and soft, smoky eyes. Chanel Celebrity Makeup Artist Angela Levin (who was also Aniston's on-set pro during Horrible Bosses) gives Us the full how-to below.

To make Aniston's blue eyes pop, Levin applied a blend of Chanel Illusion D'Ombre Eyeshadows in shimmering white and khaki shades onto her lids, then used a mix of various taupe shadows to create a very muted, fading smoky eye. Levin finished by applying two coats of mascara which gave a bit of drama to the entire look.

For Aniston's kissable, nude pout, Levin opted for a pearlized, sheer lipstick, which gave a dashing hint of color and sparkle to the lips.

Lastly, Levin applied Chanel Sublimage La Creme ($390, to Aniston's chest and arms, then added a hint of shine with St. Tropez Skin Illuminator in Gold ($22.50, to her arms.
