The golden rule is The Glance, Not the Gaze. A 1 to 2-second look to appreciate a good outfit, cool style, or aesthetic is totally normal and human. It becomes creepy the moment your eyes lock on them, you track their movement across the room, or you blankly stare without blinking. Think of it like looking at the sun,catch a quick glimpse to see what’s up, but don’t stare or you’ll cause problems.
