Sure, a woman at 5.3 feet tall is expected to weigh near 107 pounds or we say OMG she's soooo fat.. FFS people get over yourselves. However one model in particular, is in fact 5.3 and listed as 104 pounds. I bring this up because she has quite a fair amount of muscle.
I once had a truly slender stripper give me a lap dance. Before we went back she warned me. "I know I look small, but I weigh 175 pounds, is that ok?" I still got the lap dance, and she was SOLID! let me tell ya.
But that's my point. At her size and frame she would normally weigh about 140 max. (She was fairly tall mind you) However, she was so well built that she was quite heavy.
The model, as I mentioned earlier, is rather short, but her muscle tone makes 104 pounds highly unrealistic. I would expect closer to 115-120.
Hell, my GF when I met her was about the same size, and she weighed 125! My GF is about 2 inches taller, and didn't have the muscle. But 2 inches only accounts for about 7-8 pounds difference with the same frame. So for her to weigh 18 pounds more with less muscle, and the same frame? No...
My point is, in this day and age, why should we fudge numbers?
