How to test whether leggings stay opaque when you squat
Put the leggings on in the size you actually wear, squat fully in daylight, and look in a mirror with a light source behind you. That is the whole test, and it is the only one that answers the question for your body.

Why leggings go see-through when you bend
Knit fabric thins as it stretches, and bending puts the fabric across the seat at its maximum extension. Three things bring that point closer: a size that is already stretched to fit you, a low fabric weight, and a light or heathered colour.

Why leggings roll down, and what stops it
A waistband rolls when it carries more pressure than its width can spread. The top edge folds outward, and once it has folded, movement walks it down.

Why leggings pill between the thighs
Pills form where the legs rub against each other and short fibres work loose from the surface. Softer brushed finishes pill sooner, because the finish that makes the fabric feel good is loose fibre at the surface.
