Sienna Miller Just Wore the '90s Trouser Trend That's All Over Mango and Zara
Sienna Miller might have the world's top designers on speed dial but, as it turns out, she shares something in common with Who What Wear editors—a love of the high street. Over the years we've clocked her wearing items from Topshop, French brand Sézane, and dresses from Nobody's Child. However, it seems that Miller's go-to for affordable finds is Mango, a piece from which she's worn yet again this week.
This time, we spotted Miller wearing a pair of creamy cargo trousers from Mango. While her exact pair is down to its last remaining sizes (we recommend signing up for restocks, however, as Mango is one of the most reliable brands at reissuing sold-out items) that's not to say there isn't an array of very similar options you can still shop.
Mango has been backing the '90s cargo-trouser trend for a while, and Sienna Miller has just proven it is still relevant with her ensemble, which saw her style her £50 pair with a lightweight trench coat, cropped sweater, and boots—the ideal transitional outfit for the in-between period we currently find ourselves in.
Zara is another brand which has been serving up some excellent cargo trousers of late, so, whether you're still toying with the idea of trying the trend for the first time or you're already on board and are looking to expand your cargo-trouser collection, consider Sienna Miller's latest outfit your green light to do so. Scroll on to shop the cargo trouser trend.
