A great suit starts with three things: fit, fabric and occasion. Get those right and everything else falls into place.
Start with fit. The jacket shoulder should end where your own shoulder ends — no overhang, no pulling. The jacket should button comfortably without strain, and the sleeve should show a small amount of shirt cuff. Trousers should sit naturally at the waist and break gently over the shoe.
Next, think about fabric. Wool is the most versatile choice: it drapes well, breathes and holds its shape through a long day. For warmer weather, look for lighter weaves; for cooler months, a heavier wool feels right.
Finally, match the suit to the occasion. A classic navy or charcoal suit covers almost every situation, from the office to a wedding. Reserve black for the most formal evenings, and let lighter tones shine at daytime celebrations.
When in doubt, keep it simple: a well-fitting suit in a classic colour, a crisp shirt and polished shoes will never let you down.
