Fit Tips
-
Bras: The band should feel secure but not painfully tight. The cups should sit smoothly without spilling or gaping.
-
Panties: The waistband should sit comfortably without digging into the skin.
-
Nightwear: Choose your normal size for a regular fit, or size up for a softer relaxed fit.
-
Between sizes: Size up for comfort, especially in non-stretch or fitted styles.
