Let me think about this for a moment.....Hmmmmm.... What do I consider a BBW??
First she has to Big. Big is about weight with respect to what would be a normal weight for her height. She must be obviously heavier than a normal BMI (body mass index) weight for her height which often puts her in the "full figured" category.
Second, she has to be Beautiful while being big. Well WALDT when it comes to beauty, but for me she needs to be squeaky clean with lotioned soft creamy skin, nicely padded and fairly proportional measurements with ample soft breasts. There should be no skin tags, mole farms, or smelly anything. She has well kept hair, a beautiful smile, a devious sparkle in her eyes, a mani, peti and soft feet. Her beauty is completed with a kind attitude, a happy heart, a warm personality while being both very cuddly and horny.
Third, she has to be all Woman. In my book BBWs are not tom-boys or butch in any sense of the words. They are more girly, lady like, and very feminine.
