Body measurements, not garment measurements. If you are between two sizes, choose the larger size for comfort.

● Absorbent styles are designed to feel secure.
● They may feel slightly firmer than regular underwear when new.
● This is intentional — and softens after the first washes.

● High-waisted styles feel more supportive
● Lower cuts feel lighter on the body
● Seamless styles adapt more easily between sizes
