Confidence that bought a bigger hat than its head size.

means Self-important behavior or speech that takes itself far more seriously than it deserves.

from Traces back to the Latin 'pompa' meaning a procession or parade of pomp and ceremony, filtered through French before landing in English. The word 'pomp' itself carried the idea of grand, ceremonial display — so 'pomposity' is literally the personal version of a parade: all marching banners and trumpet flourish, staged by one person for an audience of however many will watch.
