Instructional diagram showing waist and bust measurement guides with illustrated figures, Japanese text, and tape measure illustrations on a light grid background.

Your waist is the narrowest natural part of your torso. Place the bottom edge of the soft tape 1–3 cm above your navel, wrap it horizontally around your waist, and measure after fully exhaling before taking a new breath.
Your bust is the fullest part of your torso. Wrap the soft tape horizontally around the widest bust line, and measure with your body upright and breathing normally.

Important note: Sizing is determined by waist/bust circumference only; height and weight are just for reference.
If your body shape stays consistent, pick your exact matching size — neither bigger nor smaller.
If your measurement falls between two sizes, choose the smaller one.
You may size down further if you purchase the extender set.
Do not rely on your regular clothing size, every corset has its exclusive size chart!
