Some people may want a slim, petite body. But be careful of what you wish for. I know a number of slim, petite women whose genetics is such that it is really hard for them to gain weight. Some wish they were curvy and could fill out a bikini better. Some have to gain weight for health reasons, and they have a hard time doing it. Some get bullied and have unflattering, objectifying adjectives thrown at them.
I intended to mention this earlier. Being a petite woman would be better than I had wanted for a long time, and that is to remain frozen in my preteen years. The problems with being an adult in a preteen body are many. I could not drive, it would be difficult to find a job, and I would not be socially accepted.
Given that, I see being a petite woman as the better alternative.
