This is completely ridiculous.
I've got bigger than average boobs and it's a pain in the ass (or perhaps the front) to get sports gear, evening dresses and other clothes. What fits on top, doesn't fit around the waist and vice versa. Not to mention that running etc is tough too - even resistance training can be tricky since it's tough to do tricep pushups with boobage in the way.
Big boobs are fine up to say a FF or G cup but after that, particularly if you're small-backed (28-32), it can be an exercise in futility to find bras that don't look like boulderholders and as for a strapless bra... no chance. No wonder that pic is taken with her boobs hanging over the top of the dress...
