The suit jacket without the suit is one of the smartest moves a man can make, and not enough men are making it. Worn with tailored trousers it reads as a proper outfit. Thrown over dark jeans and a clean shirt it becomes something easier and more current. The contemporary versions we’ve been looking at are cut with exactly that flexibility in mind, less structured than their traditional counterparts, with softer shoulders and a silhouette that works without the matching trouser. Fabric matters enormously here. A jacket that creases badly the moment you sit down is not doing its job. We’ve been looking closely at construction quality, lining weight, and whether the lapel holds its shape over a full day of wearing. These are not fashion pieces that need retiring in two seasons. They’re considered additions that earn their place by working harder than almost anything else hanging in your wardrobe.
