How do I change the way I’m wiring when it comes to clothes?

I’m getting tired of wasting money. Every morning I’m standing in the closet running through all the outfits I could wear and I never like anything. The only thing I do is buy clothes. I feel like I’m losing my sense of what I like and don’t like. If I buy something I’m walking out the store and thinking I’m a dummy, this is the only color I buy and then I wear it the next day and like it. I just don’t want to buy anymore. I see people with small wardrobes and they know exactly what they’re wearing. How do I get to that point?
