Find Your Perfect Fit
• Wacoal uses US bra sizing
• The band should fit securely and remain level around your rib cage
• Underwires should completely surround your breast tissue without resting on it
• The center gore should rest comfortably against your breastbone
• Cups should contain your breasts without spilling, gaping or excessive wrinkling
• Shoulder straps should stabilize the fit rather than carry the weight of your breasts
Fitter's Tip
• A properly fitted underwire should surround the breast tissue and sit comfortably against the rib cage
• Position all breast tissue inside the cups before evaluating the fit
• The band should provide most of the support, allowing the shoulder straps to remain comfortable
• Evaluate the cup shape as carefully as the cup size
• Try the bra beneath a fitted top to see how the shaping complements your natural silhouette
• If the band rides upward or the cups shift throughout the day, the fit should be reassessed
Care Instructions
• Hand wash after every wear using Forever & Ever Gentle Washing Powder
• Gently wash in cool water to remove body oils and perspiration
• Never machine wash or tumble dry
• Avoid bleach and fabric softeners
• Do not wring or twist the cups
• Reshape and allow the bra to air dry completely
• Rotate between bras to help preserve elasticity and support
