Morphology
The meaning is directly compositional: 'amorphous' means lacking a defined form and 'shape' means form or outline, so together they yield 'a shape lacking clear structure' without any idiomatic shift. This adjective + noun pattern is standard and cross-linguistically common, so a B1 learner who knows both constituents should be able to infer the MWE's meaning.
Etymology
Amorphous shape comes from the simple image of a soft blob, like a cloud or a puddle, that has no clear edges and keeps changing. The word amorphous means 'without a clear form' and shape is the form, so this image explains why the phrase means 'a shape that lacks a clear structure or definition'.
