Where to get Zoe Foster Blake's brilliant top from The Wrong Girl last night.

In an otherwise emotional episode, there was one shining light in The Wrong Girl last night – Zoe Foster Blake.

Yes, the author of the novel-turned-TV-show had a sneaky little cameo that had social media lighting up.

@zotheysay haha best scene ever! ???? #thewronggirl

In her role as Lily’s former intern, Foster Blake ran into Lily mid-conversation with weatherman Hamilton, played by her real life husband Hamish Blake, before the pair delivered the killer punchline after their exchange – “Who is that?”

If there was one thing better than seeing one of our favourite couples acting on screen together, it was Foster Blake’s outfit.

.@zotheysay makes a pretty good intern if we do say so. Get her style: Jumper @EquipmentFR Grace Melbourne, shirt @cosstores #TheWrongGirl pic.twitter.com/aQ1r3aL8Qj

“Wheres that jumper from?” asked one follower, while another added, “Even your jumper is smiling!”

Her simple Cos collared shirt was worn with a navy and white star-emblazoned jumper that we imagine wouldn’t look out of place in Foster Blake’s own wardrobe.

The item in question is an Equipment cashmere jumper from Grace Melbourne, the boutique where most of Lily’s wardrobe has come from.

The bad news? It just sold out.

When filming on The Wrong Girl started, I joked with (writer) Judi McCrossin that I wanted to be an extra, as a fun little easter egg for readers of the book, but I totally meant it and then aggressively followed it up with death threats etc until they conceded. Gave me some lines, too! So, don’t blink and you’ll see me on tomorrow night’s episode. (Ch 10, 8:30) And look, I don’t want to brag or anything but I was definitely a better actor than that notebook. #thewronggirl

We know – bummer.

If you are looking for something similar, we found a jumper in the reverse colours from the same label for $509.

Foster Blake's hair on the other hand... that we can help with.

She recently shared her style and beauty tips with us and they're goooood. You'll want to grab a pen and paper.
