The perfect suit jacket is a contradiction in terms. What truly makes it perfect is its ability to go well with things other than a suit. Things such as a pair of jeans and a well-fitted tee, or slacks and an untucked button down. You get the idea. The Telegraph checks all those boxes and introduces others we weren't even aware of. The Italian milled wool herringbone has just a hint of stretch, and boasts a casual fit and a deconstructed two-button style. Wear it with everything.
