How do you make a breast binder?

Most home made breast binders are made with elastic fabrics. But, people have used panty hose as well.

Another method is, to get a scarf - go for medium thick fabric scarf - and wrap it around your breasts. Then, use safety pins to secure the scarf around your chest, but be careful to not poke yourself. Then, use ACE bandages and wrap that over the scarf.

There are other ways, also.
