I had read some negative comments about silk bedding that said they're too delicate to be washed by machine or they stains literally everything! But I still decided to have a try. I mean, guys, why not? Life's an experiment itself right? Anyway I ordered from this online store whose name is also my little girls name. Now I have been sleeping on their silk bedding for about a year and a half, sheets, duvets, pillowcases, turned out all machine washed fine and everything used to be white still whitelol. I have to mention though, that when you wash them, stick to the instruction! Ask away the customer server online, their tips can be very helpful.
