Meghan Markle has attended her first major engagement on behalf of the royal family, and after she dressed down for her last public appearance, she embraced the current summery weather for this occasion.

Meghan joined Prince Harry at a reception with delegates from the Commonwealth Youth Forum at the Queen Elizabeth II conference centre in London on Wednesday.

For this appearance, the bride-to-be chose the stunning Audrey Pinstriped Stretch-Cotton Trench Dress from Altuzarra (which is available in the UK in navy from Selfridges). She paired it with a black blazer from Australian label Camilla and Marc and a monochrome Avalon Zip Top Crossbody handbag worth just £171 from Oroton, an Australian accessories brand.

The Prince has recently been given a new role as Commonwealth Youth Ambassador by the Queen and opened the Youth Forum, which aims to give young people across the Commonwealth the chance to build cross-cultural connections and networks, on Monday.

Addressing the Forum earlier this week, Harry revealed that the former Suits star is 'hugely excited' to be joining him for his new duties.

'I am also incredibly grateful that the woman I am about to marry, Meghan, will be joining me in this work, of which she too is hugely excited to take part in.'

As part of the Commonwealth Heads of Government Meeting week, we can expect to see Harry and Meghan out and about in the coming days. On Thursday, they are due to attend a Women's Empowerment reception at the Royal Aeronautical Society, London.
