平常的样子通常可以用 "usual appearance" 或 "normal appearance" 来表示。这两个词都可以用来描述一个人或物体通常是什么样子。

来源：

"Usual" 是由拉丁语 "usus"，意思是 "custom" 或 "habit"，而 "appearance" 是由拉丁语 "apparitio"，意思是 "appearing" 或 "appearance"。因此，"usual appearance" 可以被理解为 "customary appearance" 或 "habitual appearance"。
"Normal" 是由拉丁语 "norma"，意思是 "rule" 或 "pattern"，而 "appearance" 同上。因此，"normal appearance" 可以被理解为 "regular appearance" 或 "standard appearance"。

例句：

He looked different from his usual appearance. 他看起来和平常不太一样。
Her normal appearance is very neat and tidy. 她平常看起来很整洁。
His usual appearance is quite casual. 他平常穿得很随便。
The building's normal appearance is quite impressive. 这座建筑平常看起来很令人印象深刻。
