Who this is for

Adults exploring clothing proportions; no health interpretation.

How it works

This is our explicitly disclosed clothing-fit convention, not a clinical formula. Bust/hip difference above 5% of the larger circumference indicates upper-body or hip emphasis. Otherwise, waist below 75% of the smaller bust/hip circumference is described as defined; the remaining outline is balanced/straighter. Ratios are also shown.

Keep in mind

No medically validated body-type classification exists for these chosen thresholds. They are a styling convention.
Measurements do not determine health, beauty, metabolism, nutritional needs or a suitable exercise plan.
