'tastefully-organized' is a compound word combining 'tastefully' and 'organized'. 'Tastefully' originates from 'taste', which comes from the Latin word 'gustus', meaning 'sense of taste'. 'Organized' comes from the Greek word 'organon', meaning 'tool' or 'instrument'.

The word 'tastefully' evolved from the Middle English 'tasten', which meant 'to touch or test'. 'Organized' evolved from the Old French 'organiser', which meant 'to arrange'.

Initially, 'tastefully' referred to the sense of taste, but it evolved to describe aesthetic judgment. 'Organized' has largely retained its meaning of arranging or structuring.
