Band sizes are a guide, not a cup-size fitting system. The right size also depends on the cut of the bra and your bust. Support comes from the individual design; it does not increase with garment size.
03 / The feel you prefer
Fit by style
Sculpt & Front Split Leggings
Your usual size
These styles are true to size. Start with your measurements in the chart above for a close, sculpted fit.
Flow, Flared & Seamless Leggings
Choose your feel
Size down for a closer fit. Choose your usual size if you prefer a more relaxed feel.
Between sizes or choosing a different style? Check its product-page fit notes or ask us before you order.
Use a soft tape measure over underwear or light layers. Stand naturally and keep the tape level, close to your body without pulling it tight.
Bust Measure around the fullest part of your bust with your arms relaxed.
Waist Measure around your natural waist, without holding your breath.
Hips With your feet together, measure around the fullest part of your hips and seat.
Inside leg Measure from the top of your inner thigh to your ankle bone.
International size reference
Use this as a reference only. International labels vary; your measurements and the style-specific guidance are the better starting point.
