Just some quick, honest advice from me. I know this thread was started a while ago, and some good suggestion have been made, analyzed, improved on and reworked. However, that being said, out of experience into the year 2011, an important piece of the puzzle is often overlooked by the majority, and much of this puzzle piece is to be had in order to complete anyone's persona/facade (whatever you're going for I suppose). That is, 'classy' isn't defined by how you look physically, or how you dress. Of course, some people will rush quickly to the fastest searchable online dictionary, and quickly conclude from one of the many definitions of 'class' that style, indeed, plays a huge factor, and I'd be wrong to tell you it doesn't. However, you have to consider at the same time, that, some of the best-dressed individuals in this day and age can be the most uncouth scoundrels! So, I'm not going to sit here and preach how to be classy by any means, because for each person there's a veritable wall of options you can employ. Dressing stylishly will denote the respect you have for your look, and there's some vital integrity to be had there, but being classy would require that you not only look it, but you exude it. Hold yourself to a personal standard of varying degree, by no means low but by no means terribly high, and people will react subconsciously. Find out where your class comes from and amplify it, but always remember, never push it so much that your head ends up too big to fit that trendy hat on. No one likes a Scrooge.
