I've checked the posts here regarding Heather's measurements, height
and weight and have to put in my thoughts here.
I do believe her "upper body features" are real and not aided by any
type of help to get their fullness. The part about having a kid didn't
do much for the debate since Heather is way more bustier than her TWC
co-worker, Jennifer Lopez...and both ladies are moms (age is a
different story).

I think part of the questions revolve around the type of tops she
wears. Obviously, a jacket puts a hamper on her twin mounds of joy
while sweaters enhance them more--and make them appear larger.

...eh, don't know.
