Why wear clothes that are unflattering, out of fashion or just boring. Since you have to buy clothes anyway, why not only buy clothes that fit you to a T and make you feel absolutely fabulous. Whether it is the track suit or the business suit always look your best.
It is the same with taking care of yourself. It is essential to take the time and care to really take care of yourself. Get your hair cut and colored if needed, wax your eyebrows ( guys you may need to get them tweezed to avoid bushy brow) and color and make sure those legs and underarms are smooth.
