Hand Wash or Use a Delicate Cycle: To keep our products looking great, handle them with care. Hand washing is the gentlest method, but if you use a washing machine, be sure to use the delicate cycle.
Use Mild Detergent: Gentle detergents are best for our delicate fabrics. Avoid using fabric softeners and bleach, as they can damage the material.
Air Dry: After washing, avoid the dryer. Instead, lay your product flat or hang it to air dry. Keep it out of direct sunlight to prevent fading.
Store Carefully: To avoid stretching, fold your product neatly and store it in a drawer or hang it up.Keep it out of direct sunlight and humid places.
Replace When Necessary: Our products are designed to support and contour your body, but over time, they might lose some elasticity. Replace your item when it doesn't provide the same support or shows signs of wear.
