A single fit sample does not prove that every size in the range will work. A size set confirms grading, measurements, construction and appearance across key sizes before bulk production.
What a Size Set Checks
- Chest and body width
- Garment length
- Sleeve and armhole balance
- Neck opening and recovery
- Print or embroidery placement
- Post-wash measurements
Recommended Process
- Use approved bulk fabric where possible.
- Cut selected sizes from final graded patterns.
- Sew using intended bulk methods.
- Measure before washing.
- Review fit and appearance.
- Run required wash or heat tests.
- Correct grade rules before releasing bulk patterns.
Why Polyester Behaviour Matters
Stretch, recovery, GSM and heat exposure can change fit. Large and small sizes may react differently because panel dimensions and seam lengths change.
Common Problems
Extreme sizes may fail even when medium passes, print placement can look inconsistent, and neck openings may grow too much if stretch is not controlled.
Final Thoughts
A size set is one of the cheapest places to catch grading problems. Correcting patterns before bulk cutting is far easier than altering finished garments.
