Yeah, every single crotch in the manufacturer's pics is just wrong. It may be due to the model's body type—she's not fat, but looks like she's about a half-size larger on the bottom than the top, and has no defined waist, which makes things harder to fit. Her torso may also be proportionately longer below the waist. Whayever the reason, when you're wearing wide-legged, loose-fitting palazzo pants, and the crotch looks stressed while nothing else does, there's a problem.
Every single article of clothing in that haul just looks bad on Corissa's body, to the point that they barely resemble the ones shown on the model. The romper is especially egregious, but all of it's bad. Nothing is going to look good over that massive, hanging gunt, and those saggy, unsupported tits.
But Corissa is a devoted late-stage capitalist consoomer, who thinks that if she just has more choices in clothing, she can be as stylish and expressive through fashion as any skinny girl—when the truth is she's a fat, unkempt mess in every single ill-fitting thing she wears.
