Have you suddenly felt yourself in desperate need of a red cardigan?

If it seems like the social algorithm is sending urgent signals to your wardrobe, it's no accident.

Red has emerged as one of the most viral — and versatile — trends of the past year. There's almost no part of our closets it hasn't infiltrated.

Watch: Mamamia tries 'Style Maths' with Em Vernem and Basmah Qazi. Post continues below.

There was the 'Tomato Girl Summer' moment, and shortly after that we hit peak red sneaker (2024 was a very good year for cherry-coloured Sambas).

The Row's cult jelly cage sandal in transparent red took over the fashion internet, and now the brand is responsible for a coveted red flip-flop spotted on several stylish celebrities.

As a chronically online fashion person, I can't help but be influenced. Lately I've found myself searching for the perfect textured red cardi to add to my winter line-up, after noticing them popping up on my feed.

The power and pull of the red knit, as you can see, is in its ability to look completely fashion-forward, without feeling like you're trying too hard.

Throw one on with some blue jeans and your flat shoe of choice and you've got an outfit that feels on-point, polished and effortless all at once… with very little effort.

Here are the 10 options I've tracked down, with price points ranging from cheap as chips to investment-worthy.

Now I just need to decide which one is going in my cart…
