Proper care ensures your item ages gracefully, maintaining its authentic beauty for years.

Timeless Care for Every Piece.

• Store in a cool, dry, dark place away from direct sunlight, heat, humidity, and strong odours to prevent fading, cracking, or brittleness.
• Use the provided dust bag (or a soft, breathable alternative) for protection against dust, scratches, and light exposure.
• Avoid overfilling bags, over-wearing shoes/hats, or exposure to harsh chemicals (perfumes, hairsprays, lotions, sanitisers).
• Gently wipe dust with a soft, dry microfibre cloth after use.
• We recommend checking the care label for washing and drying instructions and consulting a professional for deep cleaning or repairs.
• For apparel: Hang on padded hangers; for shoes: Use shoe trees; for bags/hats: Stuff lightly with acid-free tissue to retain shape.
• Rotate usage to allow pieces to rest and recover.
