I seldom wear tie during work. In fact, I have never wore it. I can wear casual to work, with just a jean and a t-shirt. However, during my university life, we were forced to wear it 3 days a week. It is a good practice since you can learn on how to wear a tie. I have 3 ties if I am not mistaken, including silk ties that my sister bought for me. I hope they are still in good shape.
