posture braces/ bra for a 50 yr old

[mindmyarse]

Has anyone successfully used a brace to correct their posture My posture is terrible and i constantly walk with my shoulders hunched up. I do correct myself when I remember but I wondered if any one has used a brace and if it has been any good . I will roll into old age as a hunchback if I am not careful. Any advice welcome

1. Well fitting bra
   
2. Yoga or Pilates
   

I was offered a brace by a friend to help pull my frozen shoulder back. Osteopath told me not to use it as what I actually needed to do was strengthen the relevant muscles to do it instead.
