So here’s the thing about Rose Quartz. She is fat. She has fat arms and fat legs, a huge bust, a chubby face, and wide hips. But look at not pregnant Rose.
It’s not that she’s “thin” but she isn’t the “traditional” kind of fat, which is to say, her waistline is smaller than her bust and her hips. She almost certainly has a chubby pudgy tummy under her dress, but she is still an hourglass shape.
honestly draw Rose however you want, but quit harassing people that draw her as the plus sized hourglass she is. Having a prominent stomach isn’t the defining trait of being fat.
