Yup ...set them free.
Bras are bad for lymph node drainage.
Is it true that not wearing a bra is better for your breasts?
I've NEVER worn a bra and my boobs are up and firm.
I think it depends on the size of the breasts. An A or B cup, go for it. If you are a double or triple D and live in a humid climate it can just be gross.
I would ask your gyno. He/she would be up to date on all the new research.
I wear a Manzier or a Bro, and My breasts do great . . . try them.
