No, there is no hierarchy in choosing dark blue clothes. You should wear bright shoes like a model, not dark ones. Also, if you want to see if the shirt looks good, the most important thing is to see if the chest is wide enough. In fact, being thin doesn't mean that your chest is not wide enough. It depends on your own situation. Also, if your waist is as thin as a girl's, it is recommended not to wear a shirt. It would be better to wear a long suit. The shirt you chose is sportswear. However, I suggest that thin people try to wear bright clothes, because dark clothes generally look thinner, and there are no pictures, because I don't know what kind of clothes and shoe styles you like. You can ask me if the hairstyle you chose is good, and I'll give you my opinion.
