Sienna Miller Just Wore the Boot Trend Fashion People Use to Make Basic Jeans Outfits Look Much Chicer

Every fashion person knows that sometimes there's nothing more appealing than wearing an all-black outfit, and this is clearly a sentiment shared by Sienna Miller, who stepped out in London styling an easy outfit composed of head-to-toe black—save her brown tote bag—in the chicest way.

Selecting a cosy knit to set her up for the chilly weather, the actor forwent classic blue jeans and instead opted for a black pair with a flared cut. Inconspicuously layering her jeans over one of the most prevalent boot styles of the season (and every other season for that matter), Miller completed her ensemble with a pair of black cowboy boots. Refining the slouchy energy of her flared jeans with the pointed-toe shape and small block heel of her black boots, Miller created an elegant outfit that spoke to her penchant for a '70s silhouette whilst keeping things very simple with her black colour palette.

Whilst styles including moto, ankle and riding boots are also trending hard this season, the classic cowboy boot has transcended to wardrobe-staple territory, having already earned a place in the collections of most fashion people before 2024. Miller naturally opted for a minimal pair to match the rest of her understated look, steering clear of bold colours and statement embroidered motifs—unlike other pairs currently on the market that come in a range of colours and embellishments.

There's something about cowboy boots that always makes them feel so fashionable to me. Where a pair of black sock boots would have still looked chic, choosing cowboy boots is just that—more of a choice, and one that makes everything else you wear with them look more trendy by proxy. No doubt about it: Miller's flared jeans and cowboy boots pairing is one I'll be emulating for the foreseeable.
