I would be very hesitant with angling for that. While I may outwardly seem fine with getting TMs (or new TMs in this case) clothes off the floor, inside I'm starting to question how committed you are if you can't even scrounge together a pair of r&k. I'm not expecting a ton of commitment from a minimum wage job in a terrible company but at least enough where you'll stay for a few months and will show up for every shift.
At my store we don't requisition any more (unless the situation really demands it). TMs were abusing the system and just showing up out of uniform every day, hoping to score new clothes. You could always tell who the abusers were. Instead of grabbing the $10 basic polo, they'd go grab expensive shirts. Sometimes shirts that could barely pass for dress code. Now the most we'll do is 50% discount. Otherwise you'll be written up for being out of dress code and sent home.
