Please explain
I still don't understand the whole leggings phenomenon that has swept the young people of this world over the past few months.
I can understand leggings underneath short dresses to give you a bit more modesty, but honestly as pants???
I know this topic has been discussed in great depths in fashion circles, but I just had to post a pic of the leggings with zip creation selling for $139... now tell me honestly would you buy this?
