It is not necessary to use specialized collar interlining braces to suspend the collar interlining, but it can be very beneficial in some situations, especially when the collar interlining material is hard or thick. collar interlining braces can help maintain the shape of the collar interlining and prevent creases or deformations caused by improper hanging. It is particularly suitable for clothing that needs to maintain a straight structure, such as suit jackets or high-end shirts. When the collar interlining is supported by collar interlining lining, it can not only prevent the collar interlining from sagging or collapsing, but also reduce wrinkles after long-term storage or wearing, helping the collar interlining maintain a clean and neat appearance. collar interlining braces are usually designed based on the collar interlining shape and size of the clothing, so choosing the appropriate collar interlining brace is very important as it can provide the best support effect. If there is no specialized collar interlining support, using a clothes hanger of appropriate size or storing clothes flat can also help maintain the shape of the collar interlining to a certain extent.
