I saw videos on Youtube on Givenchy's Fall/Winter 2011 / 2012 / 2013 for men and I was really intrigued that they actually used what it looks like to be tights!!

Givenchy's Fall/Winter 2012/2013
I have checked out Givenchy's website www.Givenchy.com and according to the descriptions for some of the outfits from the Fall/Winter 2012 that they actually used Jersey Leggings and "wool socks"(see the Pre Collection page and you will know they aren't just wool socks) I have found a link from Luisaviaroma(www.luisaviaroma.com) that sells popular fashionable brands from Givenchy, Emilio Cavallini, Yves Saint-Laurent and etc. I'm really glad seeing that many popular fashion designers are looking at incorporating tights into their designs!
Thanks for reading!
