Creating a cohesive and functional business core wardrobe is based on several key, timeless elements, such as high-quality clothing and accessories. Quality and fit are absolutely paramount over quantity here.

A suit is an indisputable basis of the business core style. The perfect suit should be treated as an investment. The most universal and professional colors are:
