Some people have no fashion sense because they have not been taught by family members, that it is important to look your best.  No one is born with a talent for knowing what looks great on them.  It is learned behavior.  If you don’t find out from parents or siblings, you can learn to be stylish by copying the looks you see on others, that you think would look great on you.  For some people, the effort it takes to find the right clothing seems to be a burden that is overwhelming.  Even for those people, if they dress simply, keep their clothes clean, wrinkle-free, and well-fitting, they are going to look good.  Avoiding being too trendy, keeping your hair and make-up simple, and trying not to wear colors that are very bright, or have large patterns, is also a good idea.  The information is out there in magazines, online, and it even surrounds a person in school and everywhere in their environment.
