Lizzy didn't tell Lindsey how bad she looked because there's a pecking order when it comes to which of these girls gets to look good in photos. For example, if Lizzy posts a photo of herself, Lindsey, and Kim Turkington, Lizzy will look the best, followed by an awkward Lindsey, and Kim will vanish into the wall, a tree, or some other background object. If Lindsey posts a photo, generally she'll look equal to or worse than everyone else because she has no idea what she's doing. If a Halpin is involved, there might as well not be anyone else in the photo. If Hannah F posts the photo, she'll select the one in which everyone but her looks actively awful.
