Senator Gillibrand spoke to State of Politics this week about Don't Ask Don't Tell. She wore a dark suit and a blue print blouse:
Although blue is a great color for the senator, the style of this blouse is all wrong. The business of the print and the fussiness of the ruffles don't harmonize with her overall look. It sort of looks like she's wearing someone else's clothes.
Remember, you can like a garment a lot and it can still be all wrong for you. Don't get so caught up on one element (like color) that you don't pay enough attention to the other elements, like silhouette and style.
