Transtape is an alternative to chest binding for non-binary individuals.
Breast binding with transtape is the act of flattening breasts by the use of constrictive materials. The term also refers to the material used in this act. Common binding materials include cloth strips, elastic or non-elastic bandages, purpose-built undergarments (often using spandex or other synthetic fibre) and shirts layered from tight to loose. The act of breast binding is common for trans men, but is also done by androgynous and non-binary people, as well as crossdressers, cosplayers, and performers. In a general sense, women may also use binders as alternatives to bras or as a practice of propriety.
Breast binding by use of cloth strip or tape may result in bodily damage such as permanent deformation of the breast or surrounding area.
Some adolescent girls tape their breasts as they enter puberty. This is done usually for reasons of modesty (they do not want others to see them), embarrassment (they do not want others to know they have started developing), or desire to be as they previously were (they do not want to have breasts yet). This has potential risks, as the developing tissue may conform to the restricted shape, resulting in permanent deformity. Breast binding in adolescent girls may be a symptom of body dysmorphic disorder.
Transgender men, or people with gender dysphoria, as well as women who have developed larger breasts from hormone replacement therapy or breast augmentation surgery, may have motivation to bind their breasts. Transgender men and people with other gender identities (typically male presenting) may bind their breasts as an alternative to or while waiting for a “top surgery” (mastectomy) in order to be recognized as masculine presenting. Men may also find cause to bind if afflicted with gynecomastia as a means to control appearance in place of surgery or during the wait before surgery.
