FEEL GOOD FIT TIPS

Getting the perfect fit may feel a little different—by design.

Step In

We suggest you step in and pull it up over your hips. This applies to all styles, and our high-stretch fabric is built to bounce back.

Adjust the Band

Position the band low on your ribcage (front and back). This is intentional—it’s a longline design that offers all-day support by hugging your lower ribs.

Wear Straps Wide

Place the straps over the outer edges of your shoulders—away from your neck—for ergonomic comfort and posture-friendly support.

Stretch to Make it Yours

EB products are meant to mold to you. A snug first wear is normal—the adaptive fabric settles with an assertive hand-stretch or a few hours of wear, shaping to your curves without losing lift.

Our adaptive bras and tanks flex to support sizes B–J and XS–3XL, for a truly custom feel.
