Visible lines from the underwear

Short answer: Lines show when the elastic is thick, or when the brief ends in the same place as the trouser waistband. Both can be solved with a different cut.

Thick edges

A heavy elastic gives a clear line. Choose a model with a thin, flat edge. See seamless briefs.

Double edge

If the brief ends in the same place as the trousers, two lines appear. Choose a different waist height. See waist height on briefs.

The fabric of the trousers

Thin, smooth trousers show everything. Thicker fabric hides the edges by itself.

Choice of colour

Under light clothing, skin tone is least visible. See skin tone briefs.

For men

The same principle applies under smart trousers. See bamboo underpants for men.

See the range

See the models in bamboo underwear for women.

When nothing works

If the fabric of the trousers is very thin and light, even a flat edge shows. Then a thong or a seamless model is the only thing that really helps. See bamboo briefs.
