Translation of "Showy" in Japanese

This showy dress isn't appropriate for me.

この派手な服は私には向きません。

One that gets its name from a showy display of aggression.

名前の由来は 威嚇行動にあります

Since he's in show business he often goofs around in a showy way, but once in a while he has these bashful mannerisms that are really cute.

彼は芸人だからいつも馬鹿な事やっているけど、たまに見せる恥ずかしそうにする仕草がかわいいのよね。
