Guys should i buy the earring cuffs?

Im a girl and I have my hair cut uber short and I want to buy ear ring cuffs to adorn the top of my ears in order to enhance my short do look BUT i feel guilty like I feel like is it really worth about 10 bucks a cuff to look a certain way? I feel torn like my beauty is dependent on jewelry and i dont feel like its a justifiable expense...what do you think?
