If you want to bind your chest, buy a chest binder or compression sportswear, or layer 2 sports bras to flatten your chest. Before you bind yourself, put cornstarch or baby powder on to absorb sweat. Then, when you put a binder on, push your breasts down to make them flatter. Finally, wear layers of loose, baggy clothes over the binder, which can help make you look flatter, too.
