I have been thinking about this for a while and I'm glad someone asked!
I am a size 12 on the waist, and a 14 on the hip and I am a 32F. I have been described as rubenesque etc, and have debated about advertising on bbw sites. I have no idea what I am classed as! Some men have complimented me on not being slim, which took me by surprise having never considered myself big, but now I am thinking it might be a good way of getting extra custom from those men loving the curves...
I do worry that if someone sees me advertised as that they might be disappointed with a 30" waist though...
