While Claudia Winkleman is the queen of the castle when it comes to fabulous knitwear, she may have a rival in this series of Celebrity Traitors. Enter mathematician and technicolour style icon, Hannah Fry.

We're enjoying her colourful knitwear so much, it's slightly distracting us from the game. Who's got time for complicated spreadsheets and Sugababes shenanigans in the turret when we've got to hunt out where she's shopping her knits.

Well, we're not that great at hunting Traitors but we have found where to get her intarsia striped sweater. The showstopping roundtable rainbow look from episode three is from one of our favourite brands, Essentiel Antwerp.

“We wanted a wardrobe that would allow Hannah to stand out without being ostentatious; it needed to be fun and interesting and in a world that’s losing all its colour and any sense of individuality, Essentiel Antwerp is the antidote,” explains Hannah's stylist Dinah Van Tulleken.

Update: the jumper is now sold out on all sites after they were snapped up by fans of the show.

Onto episode four and Hannah was under a lot of pressure at the roundtable but she didn't go under the radar in another Essentiel Antwerp knit, this time a bold yellow cardigan with flower buttons and a white contrasting trim.

Sadly, the Jugly knit is completely sold out. But there is an updated version of the cardigan for autumn, which is available in green, brown, red or black.

It's a similar story for Hannah's pink polo top with the statement red beaded collar. Again, it's from Essentiel Antwerp and it's now sold out on the site, but you can still get it in smaller sizes from Smallable.

As for those pink PJs, grab your abacus and see if you've got any money left, because we think they're from our favourite underwear brand, Stripe & Stare. The bottoms are low in stock, but you can get them in this new black cherry colourway for autumn.
