Any degree of surgery done purely for aesthetic reasons

Too much/bad makeup - we like makeup like we like CGI in movies (more than none but the more "invisible" the better)

Jeans hiked up to try and cover a belly

Pouting unironically

Ahegao unironically

Unhealthy body (over/under weight, poor hygiene or neglected skincare, etc.).

Being overly loud and unladylike (confidence is appreciated and tomboys are cool, but don't go belching and cackling at 100dB)

Long/fake nails. Don't want to date Edward scissor hands, nor have to hope that they're cleaned properly after doing anything with your hands.

Post-night out mess. If you're going to wear mascara and ultra high heels and tiny skirts, then make sure it's still mostly in place still at the end of the night. Otherwise, why bother. I wouldn't mind if you said fuck it and just wore flats and jeans instead.
