A well-cut three-piece suit bestows gravitas the moment you toss it on. And a light, soft (not scratchy) flannel wool like this Burberry – hand-finished in Italy and interlined with natural horsehair canvas – lends itself easily to bold ties and shirts. Its versatile gray color also means you can break it up and wear the jacket, pants, and vest separately.
