At least according to Elle.com, who heard it from Cathy Horyn.
Over a week ago, while every other designer was probably furiously prepping for New York Fashion Week, Jack McCullough and Lazaro Hernandez were squeezing a little fit time in for their new denim line.
Proenza Schouler is no stranger to denim, having worked with J Brand on a line of denim that was incorporated into their Fall/Winter 2010 collection (Denim on the Runway: Fall/Winter 2010: Proenza Schouler and J Brand Collaboration).
We won't have long to wait to find out if this rumor is true as the line is set to launch around December or January. We'll be waiting and watching.
