Measure your god damn hips and read the sizing on panties on amazon. It doesn't matter if your male or female just go by the size. Of course most men are not going to have wide hips, let alone skinny ones. So you may have to settle for panties aimed at teenagers in smaller sizes. There are some panties that are aimed at traps but they're over priced respectively when a normal female pair is almost the literal exact same thing but cheaper.
I will say, the best form of lingerie for traps specifically are in my opinion assless cage panties, as I find the aesthetic similar to crotchless panties where you get to keep wearing them as you're fucked. It's quite lewd and looks very cute.
