What is “Stretchiness” and how does it work?

Stretchiness helps explain how much the fabric stretches and affects the fit.

It helps customers decide whether to size up or down.

You can choose one of the following levels:

• Non-stretch (0–5%) – no elasticity (e.g., linen, pure cotton)
• Slight stretch (10–25%) – minimal stretch (e.g., light knit)
• Moderate stretch (30–60%) – noticeable stretch (e.g., elastane blends)
• High stretch (70%+) – very flexible (e.g., spandex, activewear)
