A binder clothing is a piece of compression clothing that flattens the chest tissue, making the chest appear flatter and less present. Binders are typically worn beneath other clothing, but can also be worn on their own or as a swim top, provided the material is water-friendly. Binders are made of some kind of spandex blend in the main construction as well as a cotton panel for comfort. They can be designed to be pulled overhead, stepped into, or they could have zippers, clasps, velcro, or hooks that keep the garment snug once it’s secured in place. Binders are used by people of different genders, including women, trans men, non-binary persons, and cisgender men with gynecomastia. Binders can be a form of gender expression and can help reduce gender dysphoria or any other uncomfortable feelings that one might have about their chest. However, it is important to bind safely, as practicing improper techniques can lead to health problems such as difficulty breathing, backache, skin rashes, and deformity of the ribs. It is recommended to use a binder from a reputable company or a high impact sports bra.
