Wide hips and briefs that cut in at the side

Short answer: Choose the size by your hip measurement and find a style with a wide, soft leg edge. It is the edge, not the size, that cuts.

Where it tightens

On a wide hip the side of the brief carries the most. If the leg edge is narrow, the pressure concentrates on one centimetre and leaves a groove. If the edge is wide and soft, the pressure spreads and the problem often disappears entirely.

The size has to follow the hip

Choose underwear by the widest point, meaning the hip rather than the waist. If your hip is two sizes above your waist, choose by the hip and look at high waisted styles that do not gape at the waist. See bamboo briefs for women.

Styles that work

Hipsters and maxi briefs with a wide edge spread pressure best. Avoid narrow thong styles with thin elastic if you want to avoid marks. See bamboo underwear for women.

The material matters

A few percent elastane lets the fabric give instead of cutting. Fabric without stretch tightens exactly where the body is widest. See period briefs.

Frequently asked questions

Should I go up two sizes

Not necessarily. Try a style with a wider edge in your normal hip size first.

Why do they leave marks

Because the pressure gathers on a narrow area. That alone does not mean the size is too small.

Are seamless briefs better

Under tight trousers often yes, because the edge is bonded and flat rather than sewn.
