Braces are a must for those that do not like wearing belt or find a belt uncomfortable. The braces are not tight around the waist and have no pressure at that point. A belt has to be tight to hold up the trousers. If you have a large waist line then it can be difficult to use a belt as it may slip down and you could be forever adjusting the trousers at the waist. Braces on the other hand takes the weight of the trousers onto the shoulders and no weight around the middle. They can be adjusted to give the perfect balance between comfort and having the trousers at the correct length. The trousers will also sit better and look better when wearing braces.
