Before anything else I would like to clarify this is not an "Attack BBW's thread" so please stick with answering the title question.
The purpose of this thread to try to bring some clarity to the historically vague application of these terms in the hobby.
My image of voluptuous is the hour glass full firm breasted, proportionately smaller waist and full firm booty. Possible belly dancer pooch in tummy area or large but firm thighs.
The body tends to be on the soft side but certainly wouldn't be viewed as overweight.
I think Monroe or even Kim Kardasian.
My image of curvy would be similar but more fit especially in the belly and thighs. Also breasts and butt aren't necessarily as large but they are similar to voluptuous as far as the symmetrically smaller waist, hour glass hips, firm round butt and full breasts. Bikini model types. My ex wife and last GF both were petite, slim/trim yet extremely and naturally curvy.
I think Salma Hayek or Catherine Zeta Jones.
Amazon is a woman who is tall and large, fairly fit but may or may not possess the hour glass figure, breasts or booty size. She may even possibly be lacking in those areas. Regardless you would want her on your side in a bar fight.
None come to mind.
BBW is a kinder gentler translation of disproportionately overweight.
BBW's may or may not have any breasts size. Many do but they tend to fall or hang due to fat content. They usually have booty size but that doesn't mean it will be firm and round. It can be round or flat while large and again tends to fall or hang due to fat content. Also the limbs tend to be large as well.
Overall shape tends to be round or pear rather than hour glass.
None come to mind.
All of the above can possess a beautiful face and talented BCD skills.
How do you personally define the above categories? Please keep it honest without any direct bashing please. If any of the above ain't your cup of tea that's great but don't deliberately insult or attack the one's who aren't.
