Wonderbra conducted the survey to celebrate National Cleavage Day, with women judging breasts based on their perkiness, size and the way they sit together and, of course, their size.
Speaking about her popular cleavage in the past, Holly said: “We're so used to seeing tiny size zero figures that people freak out when they see curves. I'm a 34D/DD and no, I'd never have a boob job. I think it would cause a national breakdown if I had them enlarged. Maybe after I've had 10 kids if they're down by my knees then I might.
“But good underwear's the key. I buy firm scaffolding to make sure everything's secure and safe so there's no danger of anything falling out again on TV.”
