Elegant. Understated. Refined. All adjectives that immediately conjure up Giorgio Armani designs. But sexy? Only if you’re Megan Fox. The bombshell actress, and face of the fall Emporio Armani Underwear and Armani Jeans campaigns, hit the red carpet in L.A. Thursday night for the premiere of “Jonah Hex” wearing a dazzling Giorgio Armani Privé red silk charmeuse cocktail mini dress. To accentuate Fox’s sex appeal, not to mention killer body, Armani custom designed the dress to include a plunging neckline that cascades into a waistline ruffle motif. To offset her petite frame, exaggerated shoulders and fitted long sleeves were also incorporated to give her height and a bit of width in dimension. Fox is clearly not a fake-bake actress, so I like that she chose such a bright color to offset her pale complexion. It also looks devastatingly well against her dark skin and dark-rimmed eyes (some of her fellow actresses could follow her lead). Topping it all off was a vertigo-inducing pair of six-inch pumps with bow on back detail by Brian Atwood. She keeps things simple and to the point: sexy dress + sexy shoes + all-important youth = perfection.
