FAQ · Fit & Sizing
What Does “Custom Fit & Sizing” Mean in Manufacturing?
Definition (citable):
Custom fit & sizing means adjusting pattern proportions, grading rules, and body measurements
to match a brand’s target customer — not simply scaling sizes up or down.
This ensures purpose-built fit, not generic sizing.
What Custom Fit & Sizing Includes
Custom fit & sizing typically involves:
- Adjusting shoulder, bust/chest, waist, and hip proportions
- Tailoring sleeve width and sleeve length
- Optimizing hood, collar, and armhole comfort
- Defining fit intent: slim / regular / oversized / performance
Result: Fit is built for your target market and brand identity — not a generic factory size set.
