What to do when underwear leaves red marks

Short answer: A red mark is pressure spread over too small an area. The answer is a wider waistband or a larger size, not a different material.

Width spreads the pressure

A narrow elastic has to be pulled tight to hold. A wide band holds just as well with less pressure per square centimetre. See bamboo underwear for women.

Size is the second factor

If the band is too small, width does not help. Measure across the hip and compare with the chart instead of guessing. See guide to briefs and underwear.

When the mark stays

A mark that disappears within fifteen minutes is normal. One that stays all evening, or swelling around it, should be mentioned to your doctor.

Shrinkage can be the cause

A piece that has shrunk pulls tighter than when it was new. Wash at 40 degrees and avoid high heat. See washing and care.

Frequently asked questions

Why does the waistband leave a red mark?

Because it is narrow and has to be pulled tight to hold. A wider band spreads the pressure.

Are red marks dangerous?

A light mark that fades quickly is normal. Persistent marks or swelling should be looked at.

Can underwear shrink so it feels tight?

Yes, in high heat. Wash at 40 degrees and dry on low heat.
