Are we supposed to believe that Cassidy is more attractive than Aimee?

Before people jump down my throat about true beauty, I don't think either girl is ugly by any means. Both are beautiful IMO but I just find it hard to believe that these shallow teenage boys would see Cassidy anyone near Aimee in the looks department- yet they're trying to say Aimee isn't attractive (when Sutter is talking to his friend he says stuff like that). Cassidy is a thicker girl- you can see it when she's wearing a belly shirt at the beach party. Aimee is tall, skinny, has long legs, and long, thick, beautiful brown hair with an adorable face. I just know how shallow teenage boys think and it was hard to believe that they actually couldn't see Aimee's beauty but never questioned Cassidy.
