There were a few on the blogs during the past weeks. Yesterday there was one in Tommy Ton's Street Style section on "style.com". But today it exploded. They were everywhere. I am talking about the huge scarfs aka expensive blankets.
It seems like Vuitton started this with their 900€ one, but I can't see any reason why people shouldn't try all different kinds of blankets. This is fashion at it's easiest and most comfortable.
