Kate Middleton looked chic in an ensemble that was a combination of designer and high street. The 34-year-old royal donned an emerald green coat during a joint engagement with her husband Prince William on Thursday. She and William were raising awareness of mental health issues by visiting St. Thomas Hospital in London on Thursday.

Kate wore a green coat which she paired with a black and white patterned dress for the engagement. The Erdem coat featured round collar, long sleeves and silver chain detailing on the sleeves as well as the center. She has worn the high street British brand’s coat earlier during her official visit to New Zealand in April 2014 and at the opening of the Yokrshire leg of the Tour de France.

Underneath the jacket, the royal wore a dress by Scottish designer Jonathan Saunders. The black dress featured swallow patterns in white, three-quarter length ruffled sleeves, high neck, and button down style and pleated near the hemline. It was also cinched in at the waist with a thin black belt and showed off Kate’s slim waistline and slender frame.

The dress is from the designer’s diffusion line that he designed for Debenhams. The Jonathan Saunders/Edition line dress is from his 2012 collection and is already sold out. This is not the first time Kate has worn a bird print frock – she is a big fan of a similar Issa version, which she wore to the last wedding rehearsal at Westminster Abbey and also to the Goring Hotel on the eve of her wedding day.

The dress has a plunging V neckline and short sleeves. For Thursday’s engagement Kate accessorized with matching clutch bag and high heels. The brunette beauty paired her look with her trusted black suede Stuart Weitzman pumps and her favorite “Muse” clutch bag from the same brand.

She also wore a metal watch, small earrings and her engagement ring. Her make-up was kept subtle with a hint of eyeliner, some mascara and a slick of pink lipgloss. Her brunette tresses were left loose, center-parted and styled in waves.

William, 33, meanwhile looked dapper in brown trousers, black suit and a crisp white shirt. He aired his look with navy dotted tie and black shoes. The royal couple learned about the work being done at the hospital to prevent suicide and to support those who have been bereaved by suicide.
