Sienna Miller was the woman who defined 'boho' when she first came into the spotlight in the noughties. Since then, her style has sharpened up but still nods to the romantic look which she once made her own.
Case in point is the actress in this pretty sleeved broderie anglaise dress courtesy of Australian label Zimmerman, which she wore to the opening of the brand's New York store this week.
While the dress is undeniably spring-like and would require a hefty coat to be worn outdoors at this time of year, Miller made it slightly more suitable for February with a pair of buckled boots.
Miller has nailed off-duty nonchalance and has upped the ante with experimental red carpet dresses, such as the looks she chose when she promoted her latest film, The Lost City of Z.
Last summer, she has become the high priestess of stage door style with her daily appearances outside London's Apollo Theatre thanks to her latest West End hit, Cat On A Hot Tin Roof.
