The idea of a uniform is to instil some semblance of corporate identity and a professional manner into students at FTOs.
So, if you want to slop around looking like something from the student union bar, you'll have to do that elsewhere. So, dry your eyes and accept it.
Incidentally, the loops on pilot shirts or 'NATO' pullovers are 'epaulettes', the silver/gold rings are on 'rank slides' which fit over the epaulettes.
