To start off with a genuinely business apparel, let me present you two suits I've found searching for something to bring color to a standard black - navy blue wardrobe:

The first one is an Anne Klein New York suede jacket in sulfur yellow color. Although this color could be the last one you would look at when buying yourself some new clothes, it could be just the thing to pick up your black pants and a black top outfit. Even though it's indeed yellow color, the tone is rather subtle, and yet very elegant. The cut is good and slimming, with an interesting detail of stand collar which brings out your face. Anne Klein pants also look nice, but Neiman Marcus shop has them only in size 8, which doesn't really matter as the jacket will work great with any black pants you might have in your closet. The jacket goes for $450 at Neiman Marcus.

My second find is an Aspesi skirt suit, which is rather different from a traditional power suit, but interesting nonetheless. The skirt length falls just under the knees, which makes your legs seem longer, the jacket has an unusual collar, and the suit is made of quality wool. Why did this one catch my eye? Because of the color of course! The suit sports a mixture of light pink, green, black and white, put together very nicely to bring color, but not to shout out parrot. The unique color blend will compliment brunettes as well as blondes. A white or a black shirt will go great underneath, and simple black pumps will take care of the rest. The suit is $466 at Yoox.
