Showing good judgment about what looks, sounds, or feels attractive and appropriate; not overdone or trashy.
Tasteful comes from 'taste,' which originally meant the sense of flavor but evolved to mean 'good judgment' or 'aesthetic sense' by the 1600s. Adding '-ful' means 'full of' taste or judgment.
Your sense of taste for art and fashion actually comes from learning what others around you appreciate—it's not something you're born with, which is why 'tasteful' can seem different across cultures and generations.
