When clothes pull across the hip but fit at the waist

Short answer: Sizes are drawn around a fixed difference between waist and hip. If your own difference is bigger, nothing fits both at once. Choose by the hip and adjust the waist.

The standard difference does not fit everyone

Most size charts assume a fixed difference between waist and hip, usually somewhere between twenty and twenty five centimeters. Bodies vary more than that, and the bigger your own difference is, the harder it becomes to find something that fits both places. See bamboo leggings for women.

Choose by the larger measurement

Buy for the hip and adjust the waist, for example with a belt or a style with a built in drawstring. The other way around does not work, because a woven fabric cannot stretch beyond its own width without tearing. See bamboo clothing for women.

Stretch fabrics solve the most

A knit with stretch covers a wider range than a woven fabric, because the material itself follows the body's shape through movement. This makes knit styles a good choice when the difference between waist and hip is bigger than the chart's standard. See bamboo underwear for women.

A high waistband spreads the pressure

The wider the waistband, the less it digs in, because the pressure spreads over a larger area of skin. A narrow waistband concentrates all the tension on a single thin line, and that is where the discomfort really starts. See bamboo tops for women.

Measure both spots before choosing a size

Measure both your waist and hip at home, and note the difference in centimeters before you look at a size chart. With those two numbers you can quickly see whether a brand's standard difference matches your own body.

The cut matters as much as the fabric

An A line cut gives more room over the hip than a straight cut, even in the same size and the same fabric. Look for words like relaxed or loose fit in the description if you often feel tightness over the hip.

Always try sitting down, not only standing

A pair of trousers can fit fine standing and pull tight the moment you sit down, because the hip widens in a seated position. Always test new trousers sitting down before you settle on a size.

The season's cut varies between collections

The same brand can change its cut from season to season, so a style that used to fit suddenly pulls tight over the hip. Always check the size chart for the specific style instead of trusting your usual size blindly.
