Define "pretty," like a girl-next-door 6.5-7/10 kinda pretty, or a 8-9/10 Stacy?
I'd imagine 9/10s have to deal with constant staring, people treating you like an object of conquest and dehumanizing you, treating like you are stupid and that the only notable assets you must have are your looks, that you're a happy normie, and assigning all of these surface level, vapid personality judgments. People probably act full retard around you, and people probably like you a lot more due to halo effect.
I can only speak as a 7, but
I went from being a mousy 5/10 Plain Jane aka completely ignored, people would sit on me like in the princess diaries, teachers would constantly ask if I was a new student even though I had been there for years, to looksmaxxing to a 7ish (where in rural Kansas where I'm at, is pretty top tier as everyone is overweight and frumpy lmao), and I get complimented usually at least once every-time I go out.
I attract attention, and people usually remember me, but I have a striking/flamboyant matter of dress too (bright colors, very extra). I definitely attract less attention than Gigastacies, but people are so much nicer/more inclined to invite me to a social group, or think I'm interesting and start conversations with me. It attracts people's attention more, so you don't have to put as much effort in to attract it with personality, which is good because I'm shy/not very charismatic.
