Hi, I have just done the exam for the 1 dan, and now I have to buy a black belt. What are the differences between a silk belt, a cotton belt, and a cotton belt? I'd want to buy a cheap belt for training, and a good and beautiful belt for competition. Than, waht is the most beautiful type of belt? Why? And wich brand do you prefer? Thank you!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1
