I was so freaked out that I even wore my t-shirt inside out.
Koichi is wearing an apron when he comes to office every day.
I wore a knee-length black dress at my boyfriend’s birthday party the day before yesterday.
This word consists of kanji with hiragana attached. Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means wear so this word means to wear or to put on. You'll need to differentiate it from 着く which means (to arrive), though. Just think of how the る is the rude guy trying to get you to wear things you don't like wearing.
What do you want to wear today? How about a dress made entirely of keys (き)? Feel the metal on your skin and the weight on your shoulders. It's not a comfortable thing to put on. Maybe just stick with wearing a single key around your neck next time.
