make sure it doesn't go too low and mostly over your chest. Also I'd like to remind you not to keep it on for too much more than 8 hours, it can cause damage to your ribs.

Probabily the main reason I don't wear a binder :,) but yea, Moth's right.

If you can't breathe take it off! Dysphoria comes and goes - not breathing is permanent after a few minutes. If this keeps happening it might be time to find a new binder that fits better.
