Suit Sizing & Fitting Tips

Jacket Fit: Should close comfortably without pulling across the chest
Shoulder Fit: Seam should sit at the edge of your shoulder - this cannot be altered
Sleeve Length: Should show 1/4 to 1/2 inch of shirt cuff below the jacket sleeve
Jacket Length: Bottom should cover your seat and reach your knuckles when arms hang naturally
Trouser Length: Should have a slight break at the front, touching the top of your shoe
Waist Suppression: Jacket should follow your natural waist line
Vent Style: Single vent (British), double vent (American), or no vent (Italian)
Fit Types:
- Slim Fit: Tapered through the body, shorter jacket length
- Regular Fit: Classic proportions, moderate suppression
- Classic Fit: Roomier through chest and waist, traditional cut
Fabric Considerations: Natural fibres (wool, cotton) may require different sizing than synthetic blends
Professional Fitting: Always try on both jacket and trousers together for proper proportion
