Duchess of Cambridge makes surprise appearance and we NEED her jacket

Fabulous.

Although the Duchess of Cambridge suffered from Hyperemesis Gravidarum in the early stages of her third pregnancy, she appears to be on the mend having made three public appearances in less than a week. The 35-year-old attended a Buckingham Palace reception to mark World Mental Day last week, a party to honour children's charities on Monday and a ceremony honouring sports coaches today. Accompanied by husband Prince William and brother-in-law Prince Harry, the expectant mum was positively glowing and the epitome of casual chic.

Duchess Catherine chose a blazer by Philosophy di Lorenzo Serafini in a blue colour, a piece she clearly adores as she previously wore it in a red colour as you'll see below. It's not exactly affordable at £760 (€850) but thankfully, there are similar versions available in our favourite high-street shops including Zara and Topshop. Pairing the blazer with a black polo neck jumper, black jeans and ankle boots, Kate appeared to be in fine form as she laughed and joked with onlookers. After meeting West Ham Club Captain Mark Noble, the Duke and Duchess received matching West Ham jerseys for Prince George and Princess Charlotte, CUTE. The trio also met 150 graduates from Coach Core, the mentoring programme for apprentice coaches set up during the 2012 Olympics by Kate, William and Harry. Today's public appearance had not been previously announced and it comes just a day after Kensington Palace confirmed that the Duke and Duchess are expecting their third child in April 2018.
