I wanted my Sim to wear this top from UHK as an entire outfit, so I was looking for things that would look OK underneath it.
The default underpants go underneath but leave an annoying outline:
And then some underwear (base-game again) goes on top of it.
The same happens with the original basegame bodysuit & the recently added bodysuits from an SDX
Edit By Crinrict: Removed BG tag. It's not a thing as everything is basically BG.
