A correctly sized binder shouldn't be too difficult to put on or take off. You should be able to wear your binder for a full day (average of 8 hrs) without the binder causing breathing difficulties, pain, soreness, or extreme discomfort.
Your binder should fit snug around your body.
Your binder may be too big if:
you have to readjust your binder often
it doesn't lay flush to the bottom of your chest
there are large gaps around your armpits/shoulders
it fits like a regular tank top/doesn't bind
Aw, shucks! My binder is too big! What do I do?
Take a deep breath! It's okay. We're here to help you find a better fit in another style/size. Stop wearing your binder and reach out to us if you have any questions or concerns about how your binder is fitting!
