The first thing you need to consider is what type of style you are going for. The first, and most obvious, change in style you might come across is the number of buttons it has on it. A timeless suit that seems to fit just about all body types is the two-button suit. It is a classic, and it will likely be around a very long time. A more modern choice however, is to go with a one button suit. The rule of thumb is that generally the more buttons you have the more of a classical look you will be given off. This is because you will be showing considerably less shirt and tie the more buttons you have.
You can also take into account who designed the suits. A lot of people really like Versace suits because they have a really classic look while Gucci suits seem to be worn by people who are more along the lines of actors and musicians. Its really about portraying yourself the way you want to be portrayed.
You can also customize your Italian wool suit to get the perfect fit. A tailor shouldn't be hard to find and will usually work relatively cheaply. It is much cheaper to have them customize an existing suit that for them to make you “the perfect suit” from scratch. You will probably also be amazed with the results. The things you will want to customize will be the shirt cuff length, and the pant leg length. You should always be showing just a little bit of your shirt cuffs and your pants should always touch the floor when you aren't wearing shoes. Another rule of thumb for pant legs is that they could touch the top of the heel on your shoe.
