Meghan wore her shirt open collared, with a pretty, gold pendant necklace. (And no doubt she was wearing her favourite skinny jeans off camera, too.)

While it's difficult to see exactly what piece of jewellery Meghan chose to accompany her shirt, fans are speculating that it's her favourite Edge of Ember Kismet Charm Necklace, available to buy at £125. (opens in new tab)

Meghan wore the charm necklace to an International Women's Day school visit back in March, too, and it's clear that the pretty piece of jewellery holds special significance for her.

We love this £17 dupe from & Other Stories (opens in new tab), also. The pretty, bee embossed pendant would sit pretty on its own like Meghan's, or look chic layered with other pieces.

During the Fortune appearance, Meghan spoke about Black Lives Matter, as well as the problem of misinformation and toxicity online.

'If you listen to what I actually say, it's not controversial,' she said, defending herself against the media's misrepresentation of her words.
