I ordered it 4 weeks ago. The material is artificial. My size is S, but this is too big. It has no fastening. The reality is different from the photo of the seller. The straps are adjustable. The lace is free. But I have to say that without underwear it looks quite good. It's ideal for sex, for a partner hehe. It cost almost 2€ so for this price it's perfect. Don't expect great things for little money. I'll definitely use it in bed. If you want to wear it out, so much courage. Thank you
