How Are Leggings Hem Openings Graded Across Sizes?

Hem openings follow size-specific leg proportions and intended compression or ease.

The technical specification should identify panel geometry, placement, materials, seam construction, and measurement methods. Factories need a controlled physical or dimensional reference to reproduce the result, especially where apparently small differences can change stretch distribution, appearance, or how the garment sits during movement. Validate openings across the size set.
