That dress is definitely a fashion no-no for this woman.
Allow me to elaborate slightly.
There comes a point in every woman's life, when her boobs are no longer governed by "anti-gravity" and no longer have to be held down lest their perkiness cause them to fly off into space.
Instead, they become content to sit in place and more or less point forward.
Some time after that, "gravity" takes over and effort is required to keep them up lest they drop to the waist.
Under no circumstances should that sort of "wrap-over-the-boobs" dress be worn by a woman who is no longer in the first category. Dear Sandra has moved into category two. If not three.
