Suit Size Guide

Fit & Styling Tips

  • Shoulder: The most critical measurement — choose a size 3–5cm larger than your actual shoulder width.
  • Shirt Collar: When arms hang naturally, the shirt collar should show 1–1.5cm below the jacket collar.
  • Length:
    1. Regular (R): Suits most Asian and medium-height builds.
    2. Long (L): Better for taller or longer-torso individuals.
  • Between two sizes? Start with the larger size — it's easier to take in than let out.
  • Not sure about fit? Slim fits lean and modern; Regular fits are more relaxed and classic.
  • Size chart reference only. Actual fit may vary by brand and cut. We recommend measuring yourself before ordering.

How to Measure

1. Shoulder Width

How: Measure straight across the back from shoulder seam to shoulder seam.

Note: Posture affects this measurement — stand naturally, don't hunch or pull back.

Tip: Add 3–5cm to your measured shoulder width when selecting a size.

2. Chest / Bust

How: Measure around the fullest part of your chest, keeping the tape level.

Note: Measure after a normal breath — not fully inhaled.

Tip: Add 2–4cm ease for comfort.

3. Waist

How: Measure around the narrowest part of your torso.

Note: Don't suck in — measure relaxed, not too tight or too loose.

Tip: Add 2–4cm ease for a comfortable fit.

4. Jacket Length

How: Measure from the back of the neck (base of collar) straight down to the desired hem.

Note: The jacket should cover your seat and maintain a clean silhouette.

Tip: Standard-length covers the seat; adjust to personal preference.

5. Sleeve Length

How: Measure from the shoulder point down to the wrist bone.

Note: Sleeve Inseam is the standard measurement method.

Tip: The shirt cuff should show 1–1.5cm below the jacket sleeve.
