I’m prior service and going back active. I don’t have any uniforms. How do I go about getting them?

You’ll get re-issued everything.

You go through MEPS that last time, you raise you hand and swear in, you get your orders cut for whatever duty station. You arrive there in civvies and report. Then your personnel will take care of you from getting your CAC card, to pay to getting uniforms re-issued to TA-50. Simple as that. Do not worry about getting them before you get there, as you might lose some of it.

You will have uniforms issued to you once you get to where you are going. No need to pay anything out of pocket. Your recruiter should be telling you everything you need to know, if not ask them.
