4. Sizing and Adjustments
Accurate sizing is crucial for a well-fitting garment. Jalie patterns are known for their extensive size range. Follow these steps:
- Take Measurements: Measure the intended wearer's chest, waist, and hip circumference. For sweat pants, also measure inseam.
- Consult Size Chart: Compare measurements to the size chart provided within the pattern instructions. Select the size that most closely matches the wearer's measurements. If between sizes, consider blending sizes or choosing the larger size for a looser fit.
