There’s that fabulous black suit with the wonderful ruffly blouse underneath. Take a look at the black and white suit on the left, however, and you’ll see that there’s lots of ivory in that pattern, rather than pure white. Black and white tweed or checked patterns look grungy when ivory is paired with black. Plus, you’re so much better in cool colors.
My feeling is that the line of the suit on the left is a little out of whack. With the length of the jacket, it would be better with an elongated collar instead one that spreads out too much horizontally.
