Although clothes don’t make the man, they certainly affect the way he feels about himself. No one is more conscious of your physical appearance than you are. When you don’t look good, it changes the way you carry yourself and interact with other people. Use this to your advantage by taking care of your personal appearance. In most cases, significant improvements can be made by bathing and shaving frequently, wearing clean clothes, and being cognizant of the latest styles.
This doesn’t mean you need to spend a lot on clothes. One great rule to follow is “spend twice as much, buy half as much”. Rather than buying a bunch of cheap clothes, buy half as many select, high quality items. In long run this decreases spending because expensive clothes wear out less easily and stay in style longer than cheap clothes. Buying less also helps reduce the clutter in your closet.
