Why Your Tailor Asks About Your Dominant Hand

Your tailor isn't making small talk when they ask which hand you write with. That detail changes how they cut your jacket.

Right-handed? Your jacket gets built with the left shoulder sitting slightly lower. Left-handed? The opposite happens. It sounds backwards, but here's the logic: when you reach across your body to shake hands or grab something, your dominant shoulder drops and rolls forward. The "passive" shoulder naturally sits higher to compensate.

Most off-the-rack jackets assume you're right-handed. They're cut with a lower left shoulder because 85% of men are righties. If you're left-handed wearing a standard jacket, you'll notice the right shoulder feels tight when you move. The left side might even pull or bunch.

This isn't just about comfort. It's about how the jacket looks when you're actually wearing it, not standing perfectly still in a fitting room mirror. Watch someone give a presentation or work at their desk. Their dominant side is constantly active – gesturing, writing, reaching. A properly balanced jacket moves with you instead of fighting you.

Good tailors also adjust the button stance slightly. Your dominant hand naturally pulls the jacket when you button up, so they account for that tension. The result? Cleaner lines when the jacket is actually fastened and being worn.

Here's what to watch for: during your fitting, raise your dominant arm like you're shaking hands. Then reach across your body like you're grabbing a pen from your opposite jacket pocket. The jacket should move smoothly without pulling tight across your back or bunching at the shoulder.

If your tailor doesn't ask about your dominant hand, mention it. It's a small detail that separates tailors who understand movement from those who just take measurements. Your jacket isn't a statue – it needs to work with how your body actually moves through the day.

A well-cut jacket makes every gesture look natural. That starts with knowing which hand runs the show.
