There’s no denying that Sienna Miller has an excellent eye for a great buy. Sometimes shopping under-the-radar pieces and other times spotted in cult-classic buys, her high-low approach to fashion ensures a dynamic, elevated ensemble every single time.

Though I very much appreciate her striking red carpet looks, it's actually her off-duty 'fits I obsess over the most. Comfortable and wearable yet undeniably chic, it's here where Miller's personal style really shines. So, when I saw her in a classic trench coat from one of our favourite premium high-street brands, I knew I had to have it. However, my plans were foiled when the item in question flew out of stock before I could make it mine.

Finally, however, my fashion prayers have been answered, and Miller's Sézane Clyde Trench Coat (£275) has just been restocked in the full range of colours and sizes, including a new shade of khaki. With a classic collar and middle-button fastening, this has all of the hallmarks of an excellent trans-seasonal garment. Lightweight enough to stuff into your bag if the weather starts to brighten and roomy enough to layer over a warm knit, it's no surprise that it was such a winner the first time around.

Whilst Miller is obviously a fan of the elegant trench, I've also spotted several of my favourite influencers style the coat, as well asBest Knockoff Luxury Clothing UK's editor-in-chief Hannah Almassi. With a checkered lining and oversized fit, the trench gives any look that je ne sais quoi that French fashion is renowned for. Wearing well with jeans and tees, this trench coat can also be dressed up with a pointed-toe kitten heel and an LBD for an evening outfit you'll come back to again and again.

There are so many compelling trench coats hitting the market already this year, but I keep coming back to this specific style for its no-fuss design and elegant silhouette. Available in light beige, dark khaki, black, camel, ecru and khaki, and void of excess buttons or pockets, the coat offers a truly versatile outerwear solution that can see you through the season.
