ELI5: Why some people believe they look attractive in the mirror but unattractive in photos.

a) Mirrors aren't still images - it's easy to preen and pose and turn until you look just right. It's far easier for the camera to capture unattractive snapshots.

b) People aren't perfectly symmetrical. When you only ever look at a mirror version of yourself, seeing yourself flipped the correct way might always look a little bit "off".
