There are many different methods of tailoring, but the three most common styles would have to be English, American and Italian. The suit I'm wearing in these images has been created with a nod to traditional Napoli tailoring - A typical Napoli jacket is unstructured, with little to no canvas. The shoulders are unpadded and the crown is scalped (spalla camicia) to give it a little more room across the back.
For me, this is exactly what I need with my broader torso; having such a light weight jacket also makes it very easy to both work and play in, taking me from casual to more formal situations. The trousers were a more personal design choice with a two inch waistband, reverse pleats and two inch cuffs. I like the mid-waist and slightly cropped look to comfortably wear all year round, either with or without socks.
