For all my FTM Followers ~{Binding}~
What I have learned is to use a smaller sports bra, only 1 size smaller tho, if it restricts breathing then use your normal size, if you are using your normal size sports bra and want to later them only use 2 at max. Also layers help, like light layers and dark color clothing will be your best friend also not entirely baggy clothing but loose shirts and sweatshirts, Neoprenes This is a thick, kinda rubbery material Like wetsuits that you can use also sports compression shorts, many sports companies make these,
For Safety:
Use the safest methods you can afford, and watch out for chafing, excessive sweating, rashes and pain. If you experience any chafing issues, try wearing an undershirt or using a talcum powder under your binder of choice.If you notice any pain in your chest, give yourself a breather and try to restrict yourself to eight hours of binding at a time.If you are having any difficulty breathing or are experiencing pain, take your binder off straight away. And be sure to get yourself to a doctor or hospital as soon as possible if that doesn’t make it go away.Take breaks from binding, too. If you’ve been binding every day for a week, maybe stay home for a day where no one will see your chest, or try layering shirts for a day or two.
