The largest breast belongs to Annie Hawkins-Turner (aka Norma Stitz) (USA) who has an under breast measurement of 109.22 cm (43 in) and an around chest-over-nipple measurement of 177.8 cm (70 in).
She currently wears a US size 52I bra, the largest made, but by American bra estimation, these measurements would put her in a 48V bra, which is not manufactured.
Annie says that her record-breaking bust began developing at the age of nine "I just started growing, and kept right on. I started wearing a bra when I was in third grade, and it was a regular grown-up woman's bra. I don't remember ever weaing a training bra."
Annie was awarded her Guinness World Records title in 2000. "It made me feel like a million bucks. It's such an honour. This will go down in history. It's something I will always cherish."
