Some things just work so well together. Coffee and cake, Heathcliff and Cathy, red roses and Valentine's Day... I don't make the rules, ok?
And the same goes for fashion. There's something about the colour combination of true blue jeans and pillar box red, whether that's a manicure, a shoe, or as in Margot Robbie's case, a chic little cardigan.
The Wuthering Heights star was pictured just before Christmas in California wearing this striking colour combination, and I'm revisiting it now not just because it's almost Valentine's Day, but also because it's exactly what I want to be wearing when spring has finally sprung.
She teamed her red camisole and matching cardigan with blue jeans, a Chloe Paddington bag, a simple pair of black ballet flats by The Row and some oval-framed black sunglasses by Prada. Does it get any more effortlessly chic? I think not.

Next is really on a roll at the moment, and this elegant cardigan is a great example of why. There's a bit of volume in the sleeves to balance out the fitted waist, and it's also available in black, white or butter yellow so you can stock up when you inevitably fall in love.
Free People's jeans are well worth trying if you haven't yet. Jennifer Lopez is a fan, and the colour of these puddle jeans is spot on for wearing with fiery red.
I can't wait to swap my winter boots for ballet flats, and I just know these will go with everything in my spring capsule wardrobe. They're about £765 cheaper than Margot's pumps, which is a massive bonus.
I love the layered effect of this Mint Velvet option. It's got a little bit of wool in the fabric to give it a luxury, cosy feel, and it would also work really well with white jeans.

The Chloe Paddington bag is well and truly back, just over twenty years after its debut. The padlock is instantly recognisable and it's the ideal size for all your essentials.
This cardigan is an Amazon bestseller, and at that price, it's easy to see why. One reviewer wrote: "Lightweight and very comfortable cardigan. Ideal for everyday wear. I have purchased several of these cardigans - they wash really well and maintain their shape."
Margot has been doing the rounds to promote Emerald Fennell's adaptation of Wuthering Heights, wearing some truly incredible outfits. With the help of stylist Andrew Mukamal, she's a master at method dressing, wearing everything from Elizabeth Taylor's Cartier necklace to a replica of Charlotte Bronte's mourning bracelet.
Even in her more casual outfits, Margot's attention to detail is second to none, and I love how she styled this jeans outfit with delicate gold jewellery.
