Morphology

old + hat

The adjective 'old' clearly conveys outdatedness and 'hat' is a clothing item associated with style, so learners can plausibly infer an interpretation like 'old-fashioned' from the constituents. However, the broader idiomatic extension to 'boring, unoriginal, or no longer interesting' is not fully predictable from the literal parts and requires some exposure, so it is only partially transparent.

Etymology

The idiom old hat may come from the idea of a real old hat that people stopped wearing because it was out of fashion. So calling something old hat means it feels boring and 'no longer interesting, original, or fashionable'.
