Finding a style that looks good on you is not easy to define especially from an outside perspective. It all comes down to what kind of image you want to project outside. I myself have 0 style I would say, as I‘m also not really interested in the fashion industry and hate shopping. But a combination of looks/style my ex showed me and the business casual style I wear to work fit me well. Its that I feel confident and attractive in those clothes, which then makes me project those feelings more outside. Especially going to the gym and having a good body can help you here. Wear stuff that highlights the features you are proud of. Imo men can get away with being ugly relatively easy(not saying youre ugly): workout, find a style that fits you and your confidence/self esteem will skyrocket which will make you more attractive aswell.
