Sienna Miller Just Wore the Shoe That Makes Boho Skirts Look Modern

After two weeks of uniting fashion enthusiasts and sports fanatics, the 2025 Wimbledon tennis championship has come to an end. Demanding smart-casual attire, Wimbledon goers showcased a number of different looks that perfectly exude easy summer elegance, however, unlike previous years, I noticed that the best-dressed attendees did not rely heavily on fleeting trends. Instead, they focused on incorporating their everyday personal style into the more traditional Wimbledon attire. And one stylish celebrity who absolutely nailed this is Sienna Miller.

Spotted yesterday in a Ralph Lauren crochet crop top, white tiered midi skirt and coin belt, the actress proved once again that she can dress up for an occasion while staying true to her boho chic aesthetic. You might initially think that this outfit combo is too free-flowing for the more formal apparel expected at Wimbledon, but the actress used one key styling trick to keep to the dress etiquette—swapping out boho-inspired gladiator sandals for a pair of strappy heels.
