All our bralettes and panties come with washing instructions on the label, and you can ALWAYS wash our laundry in the washing machine, because we use very high-quality lace and materials that can withstand it very well :)
We generally recommend washing the laundry at 30° delicates in a laundry bag, because of course the following applies: the more carefully you treat the laundry, the longer it stays beautiful <3
Just be careful - as with all elastane-containing materials - with bleaching agents, especially chlorine: This will damage the elastane threads in the lace, so it's best to make sure that your detergent doesn't contain anything ;)
In general, however, one can say that machine washing our bralettes and panties is quite good :) and with the detergents that are common these days, even low temperatures are enough to get everything nice and clean again <3
