I'm writing a novel. The main character is skinny, and that I can easily relate to. She's got self-image issues where society glorifies plus-size women and labels them as "real women." My problem is writing about these plus-sized women without really dwelling on it too much. I've never been plus-sized, though all of my "BFFs" have been that body type. I just don't want to over-do any one stereotype. Her rival is, in fact, a woman with curves and she likes to shove it in the FMC's face. I just don't want any bitterness in the FMC's voice to leak into the dialogue of the secondary characters who happen to be plus-sized.
