Michael Kors suits, despite being considered a "budget brand", actually looks fairly well. Obviously it won't be as high-quality as a designer label, but for a introductory suit around $200 it fits the bill. Some of the nicer styles in the line go for more but you won't get as much bang for the buck. Ideal for a first time wearer.
You'll find these in many department stores. They for the most part have a nice modern look to them, with a tapered style. The reason for the cheaper price is the cloth quality. Know that it won't feel as nice as the custom designer labels. However, the linings, for a cheaper style, do seem to be reasonably well done and stitched. You'll want to double check on the pants linings though, as not all of them will be lined.
