None of these options are cheap – Marfa Stance coats cost upwards of £600, and the others command four-figure sums, but that’s because they take a lot more work and skill to create.

“Each piece is reversible, which means a much more constructed inside and outside, clean-finished and reinforced for constant wear on both sides,” Dant explains. “The design process involves a lot of fabric testing and quilting trials.” She adds that the customisable nature of her designs also require reinforced buttons, button holes, seams and bindings, “as the product is constantly being evolved by adding new buildable accessories.”

Wherever there is a good idea in fashion, the high street is quick to adopt. Over the past year, more affordable takes on the concept have mushroomed. Boden’s reversible puffer looks far more expensive than its (now reduced) price tag (£96, Boden). Likewise Jaeger’s reversible camel and grey wool wrap coat (£325, Marks & Spencer) and French Connection’s long quilted coat in satsuma orange and camel (£185, French Connection). The Countess of Wessex has a very on-trend reversible teddy coat by Spanish brand Indi & Cold, which retails for £207 (indiandcold.com)
