Catherine sported the Nya Penny Loafers during a visit to Castle Hill Academy for Children's Mental Health Week in February - and fans can now purchase the 'bitter chocolate' version for £89.25, reduced from £119 using the code 3PPA.
The promotion runs until Bank Holiday Monday, 25 May, subject to availability.
The loafers boast classic penny loafer styling with distinctive character courtesy of their scalloped trim and cut-out detailing.
While it appears Princess Kate wore an oxblood variant of the shoe, that shade isn't currently available - though there's a wide selection of alternatives on offer, spanning from neutral tan through to vibrant tartan (with some price differences).
Made from hard-wearing suede leather with a leather lining and in sock, they're built to look polished while remaining comfortable for daily use.
