... I think the (minimal) molding or padding is an "under-suit" and the costume is stretched over it, otherwise the "muscles" would bunch and not look natural. It was done that way for SR too.
I also think the "padding" is there for continuity from day to day.
How MOS Should have ended:
Lois: Welcome to the Planet!
Clark: Thanks Miss Lane.
Lois: Call me Lois. Come on, I'll take you to lunch and show you the ropes.
Clark: That'd be great Lois ,...but no Shawarma.
