Morphology

undersuit = suit (transparent) = under + suit

The meaning 'a suit worn under another' follows directly from the productive prefix 'under-' plus the noun 'suit' and is easily inferred.

Etymology

The word undersuit comes from two simple parts: under meaning 'below' and suit meaning 'a set of clothes', just like the familiar word undershirt. So an undersuit is a tight piece of clothing worn below a main suit, for example a spacesuit, to help keep the person warm and protected.
