I've known my girlfriend for a long time, but she never came to my home in the future. My home has always been empty, and I like to be free, so the chaos in my home is appalling. On this day, as soon as I woke up, I received a phone call from her. She said that she would come to my home, so I had to hesitate. Suddenly the doorbell rang and she stood outside my door with her mobile phone. I can't help but be surprised to see, and then look at their clothes, immediately fainted on the ground. What do you think I was wearing?
A. Jeans
B. Ultrashort wave trousers
C. Old T-shirt
D. Old fashioned pajamas
