The Duchess of Cambridge Added This 1 Fitting Accessory For St. Patrick’s Day

At this point, we know at least two things about the Duchess of Cambridge: she is a complete devotee of the structured coat, and she loves to support her favourite brands. To celebrate London's St. Patrick's Day parade, Kate did both of those things by wearing a bespoke dark green Catherine Walker coat.

It's no secret that Kate's had more than a couple of green coats in her closet, but this one stands apart with its black velvet collar and cuffs. The dark green coat fit her like a glove and had gold military-inspired buttons going down the front. She also wore matching green pumps and a pair of dazzling emerald earring by Monica Vinader. The best way she paid tribute to the holiday? The gold shamrock Irish Guard Brooch she wore proudly on her coat.
