There are some people in the world, and it is obvious, that they do not have a mirror in their house. If they did they would never have gone out the door into public waring some of the things I see people ware.
Style and fashion is not about having enough money to buy the most expensive clothes from the top designers just to "look good and fit in". Rather it is about waring clothes that work together and compliment your body style and "fit" in all the right places. It should be more about you and the way you present yourself and not so much about the clothes.
Now don't get the wrong idea and think that designer clothing is a waste, as that's not true. Quality clothing can be the bargain rather than buying something off the thrift rack. The higher the quality, the longer it will last. Not only that, it will be in style much longer too.
The trick is to shop around, find the best clothing for the money you have. Look for items that compliment your body style and work together without clashing and looking like you just stepped off the designer trane wreck. If you see someone waring something and you think they look good, make a mental note of how they look and try to duplicate the look for yourself.
Take pride in yourself and how you look and you will be very pleased. You will find that people will be complementing you, because you have confidence in yourself.
