It's a valid question, there's some smoking ladies out there with a touch of weight who look good. Personally my favorite types of chicks are the ones with a healthy look who have a huge natural rack and a bit of thickness. They're a tiny bit meaty but not quite letting it all hang out into true fattie territory, I'll take that over a flat chested bone rack anyday.
A lot of depravity on this thread so far, keep up the good work fellas..
