Okay, I feel like this is weird but I just don't wear any, lol. Sorry if that's TMI. I wear spandex workout pants in black, like from Old Navy, and then I don't have to worry about it showing through the pants or anything. To me, it's more uncomfortable to wear panties because it's more material rubbing against me and it's irritating. I guess it would depend on personal preference though. Anytime I've had trouble finding things in plus size, I just google it, like "plus size sweat wicking panties" and it usually does the trick. And I look on Amazon because they seem to have everything. Sorry, I couldn't be more helpful. Hope you find some!
