How can brands reduce see-through risk in leggings?

See-through risk is reduced by selecting fabric with reliable opacity, testing stretch behavior, reviewing color choices, and checking the garment during real movement. Darker colors may hide transparency better, but opacity still depends on fabric density, stretch ratio, construction, and sizing. Brands should review leggings during bending, squatting, and stretching, not only under studio lighting or on a flat table. Opacity should be confirmed before moving toward bulk production.
