Pay Attention—Sienna Miller Just Said This ’90s Denim Trend Is Chic Again

If I had to wittle down a list of ultimate style muses (the It-girls I look to for daily inspiration), Sienna Miller will always hold the top spot. Whilst we’ll forever credit her with defining the modern boho aesthetic, to me her style is so much more, and her everyday, low-key outfits happen to be a masterclass in elegant ease. Mixing her signature free-spirited nonchalance with sharp, London edge, Sienna manages to never look overly contrived, highly styled, or too try-hard; every look is intrinsically herself. With a mood board now full of her best hits, when I spotted her out this week in ‘90s-coded dungarees, I knew I had to pay attention.

While taking some downtime after an afternoon of retail therapy with her daughter, Sienna’s latest look was a pair of relaxed blue overalls with a loose, white tee, black Phoebe Philo slippers and a woven tote bag in classic chocolate brown. Worn with one shoulder buckled (and one casually undone), the denim-and-tee pairing felt straight out of Jennifer Aniston’s Rachel Green’s Friends wardrobe. But by pairing it with an elevated shoe choice (hello, shoe of the season?) instead of the obvious trainer, the look felt fresh for 2026.

In my opinion, dungarees are the underrated way to make your T-shirt and polished shoe feel fashion forward this season (think Miu Miu’s S/S ’26 overalls and loafers combo). And, by providing the same warmth as jeans, if there was ever a question whether or not they could look work for the colder months too, Sienna just silenced the naysayers.
