Besides this physical part, style includes a whole different field much harder to learn and play, but which has the ''advantage'' of contributing to personal development in areas other than flirting and sxxual attraction, like behaviour and success at work, manners in public places, etc. This in turn shows girls how we are in life beyond nice clothes and having a good car, for example.
Personal style and culture are things like learning to be a good listener, look people in the eyes when talking to them, have some general culture (like knowing to point in a map where is Morocco :-), naming all countries at least in its continent, have some life interesting stories to tell even if still in school, having hobbies other than watch TV and sports, like to travel and know different cultures, know how to cook something other than a fried egg, know how to speak correctly at least one foreign language, etc, etc.
Each guy should find his own style and make a coherent whole. It should be not only sxxually appealing: we have to like it ourselves, because otherwise it doesn't work and it would be a permanent exercise of acting, a lie and a sacrifice.
