During the late-night shoot at Cardiff University, Pearl showed off her svelte figure in a striped vest top and jeans.

Pearl wrapped a giant blanket over herself as the temperatures began to drop.
Meanwhile, Peter was well wrapped up with a padded jacket over his shoulders, and a long black winter coat underneath that as they filmed night time scenes for the highly-anticipated next season of the BBC show.

Pearl was cast in April to replace Jenna Coleman, who quit the sci-fi series after its ninth outing, when the show returns in spring 2017.
The theatre actress - best known for her role in The Curious Incident of the Dog in the Night Time - was announced as the Doctor's new sidekick during the FA Cup semi-final match, with a special teaser trailer showing her and the Time Lord facing off against a Dalek .
She certainly has a fan in her co-star Peter, who said: 'It is a genuine delight to welcome Pearl Mackie to Doctor Who.
'A fine, fine actress with a wonderful zest and charm, she's a refreshing addition to the TARDIS and will bring a universe of exciting new possibilities to The Doctor's adventures.'
