I agree with you. As a writer I would describe the body or what a character was wearing, how they looked in many ways. What was so wrong with that?
I think either Jemima has some complex about her own, whether she was bullying I'm not so sure, but it did seem to be a strange response when Nicole's post was about herself anyhow.
I often describe myself as 'stocky, broad-chested, or heavy-framed, it's more flattering than fat bastard with a beer gut!
But that also could be okay. My writing, my choice, I believe.
