If you want to keep that luxury feel, though, and protect the colouring, you have to make sure you take care of them properly.

My advice is for you to hand wash. If you are one of those who don’t like to do hand wash, use the cool hand wash cycle on your washing machine and turn off the spin cycle. Please make sure you use a mild detergent. 

If you are a customer in England, please don’t hang outside to get dry in the sun and don’t put them on a radiator because the heat can potentially get to the material. Use plastic clips, too; hard clips can damage the material and leave an indelible mark on the coloured sections. Keep the iron as cool as possible and damp the material down as you go to prevent it heating too much and causing potential damage.
