One of the desires of many people is feeling worthy and validated. If they can feel that way about themselves, then they will feel good about themselves. However, it is up to them to find validation within themselves. One common mistake that people make is looking for validation by trying to be others. This includes looking like the other person. One of the major issues with this approach is that people are not going to feel validated no matter how much praise they get from people. They are still going to feel incomplete because they will feel that their true selves will not get acceptance.
People try to fit in with fashion among many different ways. The only issue is that they do not truly transform themselves. They instead conform when they dress like others. As a result, they do not get validation. If people get validation, it is not them that gets it but the act and the image they present to others. However, when they do what others are doing, they do mention feeling good. When they post it on social media, they get a lot of praise which can help them feel confident.
For those that are a little more unique in tastes, it may help to find their own validation. They would be amazed how people will react when they present their true style to others. For one thing, they will come across people who actually truly like them for who they are. Then they will experience real validation and confidence, partially because it has started from within.
