Sienna Miller’s High Street Trench Coat Is Finally Back In Stock, After Amassing A 40,000+ Waiting List

Not all trench coats are created equally. How do I know this? Well, when Sézane produced a cotton, slightly oversized version available in five different colours – dark khaki, light beige, black, ecru and camel – with a checked lining, it proved to be so popular, it had to be restocked five times and amassed a waiting list of over 40,000 people.

Of course, it helps that Sienna Miller wore it while in Paris during February of this year. As we all know, anything she wears – whether it's the perfect rainy day outfit or anything from M&S – flies off the shelves, thanks to her winning combination of looking simultaneously glorious and somehow also relatable. Luckily, Sézane is responding to the demand for this spring-ready coat, which has just been restocked in black, camel and dark khaki as of this week.

Chances are you've heard of Sézane. Perhaps you're an obsessive follower of the French brand, or perhaps you simply heard it mentioned by a friend. Maybe you have no idea what I'm talking about, so it feels pertinent to inform you that Sézane has one of those fervent, excited followings that always tends to happen whenever anything identifies as French.

As well as Miller, who has worn the brand several times, other celebrity fans of Sézane range from Selena Gomez to the Princess of Wales. And, of course, Grazia's Gavi Weiss, who took the cult trench coat for spin with straight-leg jeans, square-toed boots and shades. The secret of Sézane's appeal? All of the clothes possess a timeless, elegant quality. They feel well-made, they're easy to wear and they really do last – season after season.

Having said all that, I probably don't need to stress that this trench will likely experience the same sort of success again. So, if you don't want to find yourself as person 40,001 on a list of trench coat fans once these restocked shades inevitably sell out, I'd suggest you act fairly quickly.
