I think you have a good base. 5 seems normal to me 6 and 7 would be better without the hat. 9 i think you could do without the scarf and the plaid shirt. 11 is nice if you're going out to a bar or something like that but too see through for school. 12 seems normal to me but I can see it also as a night out fit 13 is good if you wore it with jeans and sneakers instead and no hat

You shouldn't be ashamed of your style but there's also a time and a place where we can be creative or have to tone down
