Barrel leg jeans—the voluminous, architectural, and surprisingly flattering style—have made their way into the mainstream. Think elegant, ladylike pairings that balance the jeans’ volume with polish; minimalist all-black ensembles that let the silhouette take center stage, and playful mix-and-match looks anchored by cool-girl sneakers. Light-wash barrel jeans from Citizens of Humanity add a relaxed edge to a ladylike knit and mules, making the whole look feel cool, not fussy.
