Well, her overall chest size is pretty ridiculously unhealthy, but her band size really kills it. The 36 refers to her chest below the boobs, which means that her waist (further down) isn't too far off- especially since fatties usually expand in that muh curvez inverted hourglass, her waist is probably at least 40 inches. I don't totally know what the healthy range of sizes is, especially since some women just have naturally big tits, but if you check out the bra band project a lot of people start getting noticeably obese at 34 band size, down to 28 sometimes if their tits are big enough.
