I have this vague recollection of 2007 being the Year of the Chemise Gown in my costuming circles. I think it started off with Katherine, who spontaneously decided that she had to have one, and then others rapidly followed suit. Yeah, costumers are kind of sheep like that. ;)
At the time, I remember thinking “Why on earth would you want to wear a boring white cotton dress?” Well, seeing Katherine and my other friends at Costume College the following year changed my mind.
