I don't think they're real silk - in the snippets she shared yesterday it said something about the scrunchies being made from offcuts of the pyjamas which are made from recycled polyester. So just like the generic polyester satin pyjamas you can get from most high street fashion brands.So grace really doesn't care about selling "sustainable silk" scrunchies and pyjamas lol
I hate those polyester satin pyjamas though. Never understood the appeal of wearing such an unbreathable fabric to sleep in, I feel like you'd be so sweaty!
