“Showy,” “pretentious,” and “ostentatious” all mean given to outward display, but there are subtle differences in the meaning of these show-off words. “Showy” implies an imposing or striking appearance, but usually also implies cheapness or bad taste. “Pretentious” suggests an appearance of importance not justified by a thing’s value or a person’s standing. “Ostentatious” is the most peacockish of all, stressing the vanity of the display.
