TIPS TO FINDING YOUR RIGHT FIT

  1. The Center Fit

    The center front should sit flat and flush against your sternum. If it floats or lifts away from your body, your cup size is likely too small.

  2. The Band Anchor

    Your band provides 80% of the support. It should sit level and parallel to the ground all the way around—even when you lift your arms. If it rides up the back, size down in the band.

  3. The Strap Balance

    Straps should feel comfortably secure without digging into your shoulders. Adjust them to stabilize, not to do the heavy lifting.

  4. Seamless Coverage

    Your breasts should sit fully within the molded cups with no spillage at the neckline or underarms. If you notice tissue overflowing or cups shifting, size up in the cup.

  5. Between Sizes?

    Our sculpting fabric adapts to your curves. For a more snatched, high-support hold, size down. For everyday relaxed comfort, size up.
