How to avoid see-through issues in light-colored leggings?

To avoid see-through issues in light-colored leggings, material selection and fabric construction are critical before approving bulk production. Evaluate fabric opacity under tension, especially in areas subjected to stretching, such as the thighs and seat. Blends with higher spandex content can reduce sagging but may increase transparency if the knit is too thin.

At the manufacturer level, check fabric weight, stitch density, and loop structure. Thin fabrics, uneven knitting, or low stitch density are common causes of transparency in real production. Perform both static and dynamic opacity tests on pre-production samples, stretching them to intended wear dimensions under bright light to detect weak spots.

Additionally, inspect dye penetration and consistency, as uneven coloring can worsen see-through effects. Avoid relying solely on swatches; full-size garment samples better reveal fit-related transparency. Pre-approving these samples ensures that bulk production meets opacity standards, preventing costly reworks, returns, or unsellable inventory.
