Bean, I was having issues with that last week, but I received wise advice to reach up to your Sq/Gp exec staff to request assistance. If the uniforms are something your unit agrees to provide, they can point you to the right person or resource. Through a few phone calls and favors, mine was able to point me to a flying squadron that had an extra supply which is another avenue you could try.
Brings me to a uniform question: does anyone know what color each UPT base name patch is supposed to be? I was told from previous IFT classes that your assigned UPT base typically has an associated color for the name patch, which makes it easy to see who will be going to which UPT base at a glance during IFT; since I haven't gotten any indication of my UPT base, I'm tempted to make 3 different ones...
