During my last deployment, my family moved my stuff into storage and lost (among other things) my class A uniform.

Now Im being told I need to get my Class A's squared away for some upcoming events.

Yesterday, supply told everyone they can't order any class a's, so dont even ask.

Am I just going to have to pay for a new set with my own money, or is there some way around this?

Sounds like you are going to have to buy a new Class A uniform. How long you been in? I used my issued one until it didnt fit anymore (no I didnt get fat)...but I got lucky and didnt have to buy a whole new set!!
