I love the mystery and sophistication that is associated with the lace face. I'll love to try it out soon maybe on a shoot or something.You'll most likely see this trend on the runway or in editorials rather than on a red carpet or on the streets.
While you may look weird walking around with your face covered in lace, you could still try to inject some mystery into your look say on a trip to church in a stylish retro inspired hat with lace/net covering coming down to the face à laPippa Middleton. You can find a lot of them around in accessories shops. If you have a plain hat, you could get some lace fabric or net and DIY.
