She accessorised her ensemble with gold bracelets and was pictured laughing with friends on her day out.

Malin shares son Sebastian with her ex-husband Roberto Zincone, whom she met in 2003 when they played together in a band called The Petalstones.
The couple married in 2007, but divorced in 2014. She's now married to British actor Jack Donnelly.
In 2019, she revealed her little boy wanted a brother or sister.
'We've talked about [siblings] before,' she told Us Weekly, at the time. 'He's curious about it. I don't think he actually knows what it means! I think he wants a sibling his age, which would be interesting. But we'll see.'
At the time, she also stated the topic of expanding her family was 'always in the conversation' but was a 'big responsibility.'
'It's a beautiful vision, and we'll see what happens,' she said.
