This is the “Rubik” wrap coat woven with a striking houndstooth design. It has a high neck, concelealed button front and a self tie belt. It is by Reiss.
The coat is nice enough but I am not a big fan of the houndstooth pattern.
1- The Duchess of Cambridge wore it on 10th December 2015 to visit the Centre for Addiction Treatment Studies in London.
2- Kate wore it again on 12th December 2015 to do some Christmas shopping in London.
