you should have a very clear idea
You should have a very clear idea about what you want before you even walk into a clothing store to find something like pants or shirts. One of the major things to think about is what kind of style you want for yourself. If you look at the clothes that people wear on a regular basis, you will typically find that there is a common pattern in the kind of pants, shirts, and other articles of clothing they choose to wear. You need to come up with your own unique way of dressing, and once you have an image of what that looks like in your head, it will make buying clothes so much easier and even less expensive.
