Calvin Klein is synonymous with all-American minimalist chic. What began as a coats range in 1968, quickly expanded into a full ready-to-wear collection, not-to-mention those namesake designer jeans. In 2003, Klein handed the reigns to protégé Brazilian Francisco Costa who continues to impress a roster of celebrities that includes Jennifer Aniston and Katie Holmes with his interpretation of the label's easy pared-down elegance.
