According to the CFDA, the Council of Fashion Designers of America, the date blocks for both the spring 2012 and fall 2012 shows have already been confirmed. As per their website, the Spring 2012 collections will be shown from Thursday, September 8 through Thursday, September 15, 2011. The Fall 2012 collections will be shown Thursday, February 9 through Thursday, February 16, 2012.
It has already been reported that Victoria will be showing on September 11th but as of right now, I have yet to see that date confirmed on the Fashion Week schedule. I will definitely be keeping you all informed on when and where she will be showing her newest collection as soon as I find out more info. Stay tuned!
