The nice thing about the school district I work for is that teachers don't have a dress code. I dress casual. Levi's 501's are the most comfortable jeans that I've found. I dress comfortable. So I dress really casual. I don't think I've ever worn out any other pair of jeans at work. But I go through about two pair of Levi's a year. Worn out in this case are small holes so the jeans are able to be recycled for work on the farm. Again, comfort is a premium. Should you wear Levi's 501's? It's all a matter of taste. I have it, and I must say that when I used to do office work, my bosses didn't. I had to work overtime to gain Casual Day Certificates to wear 501's. Really, it was worth it. Did I say this yet? They are comfortable.
