Understanding Suit Sizes
Size Systems
Suit sizes vary by country and region. The main sizing systems are:
- US/UK: Based on chest measurement in inches with a letter indicating length (S=Short, R=Regular, L=Long)
- EU: Based on chest measurement in centimeters
- Italy: Similar to EU but with slight variations
Length Categories
The length category determines the jacket length and sleeve length:
- Short (S): For men under 5'7" (170cm)
- Regular (R): For men 5'7" to 6'0" (170-183cm)
- Long (L): For men over 6'0" (183cm)
Fit Types
Modern suits come in various fit styles:
- Classic/Traditional: Roomier throughout with a fuller cut
- Modern: Slightly trimmed down from classic with a more defined shape
- Slim: Tapered with narrower shoulders and sleeves
- Tailored/Ultra-Slim: Very fitted, close to the body
Measurements Guide
For accurate measurements:
- Stand naturally with arms relaxed at sides
- Wear a dress shirt but no jacket
- Use a flexible tape measure
- Don't pull the tape measure too tight
- Have someone else take measurements when possible
Perfect Fit Tips
Even with accurate measurements, most suits will need tailoring for a perfect fit. Here are key areas to check:
- Shoulders: The jacket shoulder seam should end at your natural shoulder edge
- Sleeve Length: Should show about ¼-½ inch of shirt cuff
- Jacket Length: Should cover your rear and fall to the middle of your hand when arms are at your sides
- Buttoning: When buttoned, there should be no pulling or excess fabric
- Trouser Break: The amount of fold where pants meet shoes - from no break (modern) to full break (traditional)
Remember that different brands and designers may size differently, so don't be discouraged if your size varies between labels.
