My favorite clothes is a T-shirt my cousin got me, it's like a lucky charm for me.
And here's the story.
When I was in middle school, I was super allergic to math, maybe I just didn't have it in me to learn that, 'cause no matter how hard I tried, I just couldn't get good grades. So I was pretty frustrated, you know.
And one day, I got a gift from my cousin, which is the T-shirt I mentioned earlier. It's super comfortable. I mean, it's made of cotton, so the texture is quite soft, and it breathes well, so it's really comfy to wear during summer.
And what's unique about it is that it's a specially designed one, I mean, she had the shirt printed with functions and equations in math, so when I was wearing it, I was like a walking math textbook.
She said, this is a magical T-shirt that could help me improve my grades. Well, to be honest, it sounds a little bit superstitious, and I didn't buy it at first, but believe it or not, there's really something magical about this T-shirt. After a while, somehow, math started to grow on me. Maybe it's because I suddenly got the hang of it or maybe it's the new math teacher. Anyway, my performance in math did improve a lot.
So that's why I called it my lucky charm, and so far it's definitely my favorite clothes.
