Just focus on studies
For shoes you should consider buying black superga's off amazon or ebay, that's what I did and I love them. For a bag you could try and find a nice satchel from somewhere cheap like h&m :)
Aww, I know how you feel :) I like to be different too. Well I don't know where you are from so can't really recommend anywhere.. but look for something unique and something that you like.. that's the main thing! :0 Hope I helped! Could you answer mine please?
