Sienna Miller is responsible for many things. Introducing us to honey blonde, an M&S collaboration that sold out in record time, wearing Ugg boots to Glastonbury (2006, how we miss all your gloriously unhinged trends) and reminding us that boho is always the answer. While most of us have safely packed away, or even sold, our platform wedges, Canadian tuxedos and suede belts from the 2000s, Miller's latest outfit has got me rethinking everything.
Miller recently attended her sister's Bridal Ballerina Breakfast in an outfit that reaffirms that, yes, boho is back. There have been rumblings of a boho renaissance in the fashion industry for a while now - just one look at Chloé's spring/summer 2025 show tells you everything you need to know, with its copious amounts of lace, pretty florals and crochet. Miller's take on the trend, however, is distinctly 2025 - boho but with a polish that feels effortless rather than nostalgic.

Her outfit formula was simple. Denim trench, patchwork jeans, and the perfect Chloe blouse complete - of course - with a pair of suede ballet flats and a suede tote - the perfect cherry on top of this bohemian revival's cake.
This isn't the first time this season Miller's outfit has left us in awe, either. Just last month, Sienna Miller's white jeans and leather vest combo was the talk of the town at Grazia HQ, as was her perfect denim jean campaign with Frame.
While the majority of Miller's outfit comprises of designer items, we've found the best high street alternatives below.

This denim trench, available on M&S is also a close match to the exact style Miller was spotted wearing on Tuesday. It even has the same single-breasted design, longline silhouette and short lapel collar. Style with cream jeans and loafers.
Patchwork jeans
Nothing says boho more than a pair of patchwork flare jeans. While Miller's Chloe pair are now out of stock, the high street is glittered with equally cool options.
