Flare jeans | Flare jeans are a style of denim that features a fitted silhouette through the thigh and then gradually widen from the knee down to the hem. This creates a "flare" effect, reminiscent of styles from the 1960s and 1970s. They often provide a retro look and can be paired with various tops, from fitted shirts to flowy blouses, and work well with both casual and dressy outfits.
