Morphology

monkey + suit

Although both constituents ('monkey' and 'suit') are known, the combined meaning 'a formal suit' used humorously or mockingly is not directly compositional: a literal parse suggests a suit for a monkey or a silly costume. The expression depends on cultural/derogatory metaphor (deriding formal wear), so a B1 learner who only knows the words would only partially infer the intended sense and would likely need exposure or cultural knowledge.

Etymology

Monkey suit may come from the picture of circus monkeys dressed in small human suits, a sight that looked silly and more like a costume. So people began calling real formal clothes a 'monkey suit' to joke and to mean 'a formal or ridiculous outfit'.
