'perfectly-shaped' is a compound formed from 'perfectly' (from Latin 'perfectus', meaning 'completed, excellent') and 'shaped' (from Old English 'sceapian', meaning 'to form, create').

'perfectly-shaped' combines the adverb 'perfectly' and the past participle 'shaped', a pattern common in modern English to describe ideal forms.

Initially, the components meant 'in a perfect manner' and 'formed', and together they evolved to mean 'having an ideal or flawless form'.
