Sean Connery as James Bond in Dr. No (1962).
An oft overlooked point of personal style is how a man carries himself. Standing up straight(er) at the very least will enable you to project more elegance, greater self-confidence, and help your clothes look better on you. Your body language also has no small effect on how you feel about yourself. Surprise! I stumbled onto these related points recently in my usual evening meanderings around the 'net. Here is what a few others have to say on the matter:
You should always be conscious, as much as possible, of your posture. Even if you don’t yet own a perfectly fitted suit, start paying attention to how your body interacts with your clothes. A great dose of elegance can be obtained through the right mindset and attitude. Posture is one of the least commented upon elements in the field of men’s style. Yet, the way you stand in your clothes is extremely important. We’ll have the opportunity to expand on this subject another time. -- Hugo Jacomet, Parisian Gentleman
