I got into NovelAI again, and I'm having impossible trouble generating girls with impossibly round boobs and impossibly thin waists. What tags should I use for it, and does anyone have pics like that to use as vibe transfer images?

Thus far, the best results have come from using {{huge breasts, spherical breasts, fake tits, round breasts, giant breasts, gravity-defying breasts}} in the prompt, but even that isn't as big or firm as I'd like. Hyper breasts can generate tits that are even too big, but they're also extremely saggy. And for slimness I've been using {{thin, small waist, slim, slender, skinny female, anorexic}}, which is so far from skinny that it's ridiculous. Am I doing something wrong here, and is anyone else here using NovelAI?
