How Should a Business Suit Fit? A Head-to-Toe Checklist

A good business suit follows your shape while leaving room to sit, reach and walk. In the photos from the original article, the two suits were worn by the same person. The less expensive one sat better through the shoulders and looked cleaner from the front.

Wear the shirt and shoes you expect to pair with the suit. Fasten the jacket’s main button while standing and look at the front, side and back. Then unbutton it and sit down.

Check the jacket from the top down

• Shoulders: the sleeve should drop cleanly from the shoulder, without a pronounced dent or bulge.
• Collar: look for a close, even meeting with the shirt collar at the back.
• Chest: lapels should lie smoothly and the front should close without sharp lines pulling from the button.
• Sleeves and length: check both wrists and see how the hem looks from behind. A classic jacket generally covers the seat.

Check the trousers in motion

Walk, sit and put your hands in your pockets. Watch for flaring pocket openings and fabric straining across the thighs. Check the hem over your usual shoes. A slight break is one option; a clean no-break hem can also work.

If you’re comparing two sizes, prioritize the shoulders and chest. Sleeve and trouser hems are often easier to change. Ask for the alteration cost before comparing the final prices. Proper Cloth’s tailoring guide explains common limits.
