Some of the strong coloured clothes made for your dolls (even official ones) may stain their bodies so put them through a coloured wash if you have any doubts about an item of clothing.
If you plan to wash your dolls clothes, put them in a little washing bag for delicates and don’t put dark dolls clothing in with whites!
Store your dolls in light colored clothing and without shoes as they tend to stain the doll’s skin especially when piled up on eachother.
Ziplock bags are great for keeping your dolls and accessories dust free, they come in many different sizes
If your doll has red colored hair (this includes all pinks and ginger colors), keep them out of direct sunlight as their hair can fade.
Use fabric hair ties when possible as rubber bands and most elastics tend to melt or disintegrate. The elastics provided with your doll by Mattel or MGA are of a better quality, they can be used safely.
