Frequently Asked Questions
How should a men's suit fit?▾
Jacket shoulders at yours. Button without pulling. Sleeves showing about 1.5cm of shirt cuff. Trousers at your natural waist, breaking slightly at the shoe, room to sit comfortably. Modern fits are slimmer through the body and leg without being tight. If buying preloved, budget for tailoring, it transforms the result.
What colour suit is most versatile?▾
Navy. Works for business, weddings, formal events, and pairs with virtually any shirt and tie. Charcoal grey is equally adaptable. Black is best for very formal and evening occasions. Start with navy and grey, then add mid-blue or tan.
Is it worth buying a preloved suit?▾
One of the smartest things you can do on SO-ME. A preloved designer suit in wool or cashmere will outperform a new budget suit in fit, drape, and longevity. Have it dry-cleaned and tailored to your measurements, even hemming the trousers and adjusting the waist makes a dramatic difference.
