Wide leg pants aren't everyone's cup of tea, but Sienna Miller isn't one of those people! We love the idea of a nice pair of navy pants like these for a slightly more dressed up look rather than wide leg jeans, and she shows us how to keep them casual too with her sneakers and a cute top with tiny cutout details! This super fun crochet top from Lulu's will keep you cool in the summer with these navy trousers, and really any sporty sneaker would do the trick here - even a fun colored pair!
