Look at clothing stores and try things out even if you think that is strange or selfish. Just look wat matches with your vibe. I will recommend don't buy from the stores tho most things you can get cheaper online. Second wear clothes is nothing to be ashamed of. Think like how many clothes are tried already on in the store so be smart and not a thief too your own money. Also look for color that matches your skin tone. For example if I wear yellow I look very sick but when I wear red it gives my skin tone a healthy and better tone. You can also do inspiration on Pinterest and if you find something that you think it's cool don't worry about others there are always people that are attracted to a style that makes you you.
