OK, update time…
I e-mailed corporate (Thanks for the link, Bosda Di’Chi of Tricor) but haven’t heard back other than a form letter assuring me that my concerns will soon be attended to yet. I’ll let y’all know when and if I do.
I guess I was in single mom mode, Canvas Shoes. Pink sweats, an oversized t-shirt, and my jacket, but I did have my work ID badge on, identifying me as a researcher at the local medical school. I’d think that would counteract some of the negative impression my somewhat haphazard outfit may have caused, but who knows. I’ve wracked my brain trying to figure out why they singled me out, but have no idea. I went into the store, made a bee-line for the registers (which are out of sight of the entrance, oddly enough), gave my merchandise to the cashier, went directly to the mens department, wandered around ten minutes or so max finding the appropriate sizes, and went straight back to the cashier.
I’m assuming that during the ten minutes or so after Manager 1 went to go fetch Manager 2, they reviewed the security tape of my time in the store, verifying that I did indeed bring the items in with me.
I would think that a shoplifter would either steal the right size in the first place, or if realizing they had the wrong size, would just steal more in the appropriate size, rather than drawing attention to themselves by exchanging the items. What do I know though?
That really blows about the gloves, Cinnamon Girl. What on earth are you expected to do with two right hand gloves? 
I’ve calmed down quite a bit by now, of course, but what a way to ruin Christmas Eve. And wouldn’t you know that my son wants to exchange one of the pairs of pants for a different brand now? Don’t suppose he’d have any luck exchaning them at Bed and Bath, Cherry2000? (just kidding!)
Thanks for all the support guys!
