Agree with Chinagirl that the definition will vary between people. For me, curvy is hourglass. It's all about chest/waist/hip ratio. Slim girls can be curvy if they have the bone structure and big girls can be curvy if they have a waist. Elle McPherson is curvy and so is JLo
That being said, I'm concerned that this thread is going to degenerate into fat and skinny shaming comments. Hoping we don't go there peeps.
Never regret anything that has happened in your life. It cannot be changed, forgotten or undone. So, take it as a lesson learned and move on.
