It's a seemingly timeless institution; the modern suit is the result of nearly a thousand years of evolution. Its current form has changed very little in the last 200 years, and in spite of great efforts to do away with it, the suit boldly promises to be around for many years to come.
Comfort-driven measures like casual Fridays have bled over the other four days of the work week, and many companies embrace a dressed-down appearance for normal days in the office. However, even more casual companies expect applicants for employment to wear a proper business suit for interviews, important meetings and business-to-business interaction. Many trendy renditions of the classic suit are available for purchase, and if a job hunter doesn't take care, may wind up inadvertently purchasing some nonsensical article of sartorial whimsy that brands them negatively on the occasion their appearance matters the most. This diagram gives a quick but thorough overview of a proper suit and everything that goes with it. Move the cursor over the items to read their descriptions at the bottom of the page.
