Lining playsuit pants?

I am a beginner, but I have made three tea party pantsuits without issue. I recently bought some seersucker that seems pretty light and I would like to line the pants as well as the yoke. Could someone point me in the direction of a tutorial that might help with this? I want to put snaps in the pants for diaper changes, and am worried that might complicate lining the pants or be above my skill level.
