Where to find Meghan Markle's chic blouse

Meghan Markle made a sneaky trip to the National Theatre in London yesterday, visiting the Immersive Storytelling Studio, looking chic in an all-white ensemble.

The Duchess of Sussex is the theatre patron, a role which she'll retain even when she steps down officially as a senior royal.

Meghan posed in front of a hologram of jazz singer Nubiya Brandon, in a white puffy sleeved Topshop blouse and a white Roland Mouret pencil skirt with a black handbag and simple jewellery.

The organza button sleeved blouse is available from the Topshop website, for US$55 (AU$84), although it's already selling out fast.

According to the SussexRoyal Instagram account, the Duchess was visiting the the Immersive Storytelling Studio in London, where technology like Virtual Reality is "being used to develop new forms of emotive storytelling."

The post also detailed that Meghan and her husband Prince Harry also recently visited Stanford University, where they took part in another virtual reality presentation that "allows the user to experience life through another person's point of view."

"The goal of this method of virtual reality is to enable us to better connect and empathise with each other as people, regardless of race, age or nationality" the post continued.

The Duke and Duchess of Sussex are currently in the UK for a final series of events before they officially step down as senior members of the Royal Family.
