To preserve the beauty, fit, and comfort of your lingerie, we recommend the following care guidelines:
1. Routine Freshening
• Lightly dust or wipe your lingerie with a soft, dry cloth or gentle fabric cleanser to maintain its appearance between wears.
• Always handle lace, mesh, and delicate trims with care to avoid snagging.
2. Washing
• Hand washing is strongly recommended. Use lukewarm water with a mild detergent formulated for delicates.
• Gently swirl the item—do not scrub, twist, or wring.
• If machine washing is necessary, place the lingerie in a mesh laundry bag and use a delicate cycle with cold water.
3. Detergent Choice
• Use a gentle, pH-balanced detergent free of bleach and harsh chemicals.
• Avoid fabric softeners, as they can damage elastic fibers and reduce stretch recovery.
4. Drying
• Do not tumble dry. Heat can deform underwire, elastics, and lace.
• Lay flat on a towel or hang to air dry away from direct sunlight or heaters.
5. Stain & Spot Care
• For minor spots, moisten a soft cloth with a mild detergent solution and dab gently—never rub.
• Rinse the area with cool water and air dry.
6. Storage
• Store bras and lingerie flat or in a drawer with soft dividers to help maintain their shape.
• Avoid over-stacking or folding molded cups and wired items.
7. Fabric & Fit Preservation
• Rotate your pieces to prevent overstretching and fabric stress.
• Avoid wearing jewelry or accessories that could catch on lace or mesh.
