Ooh wow ahah! You figured it out pretty well. Don’t remember the exact score everything gives but seems about right.
I think the skirt gives most score even if it’s not see-trough. Socks give less points than bare because more skin. And shoeless no socks gives most because feet. Hairstyles give most if they match, or the sum is divisible by 2, just a random rule I came up so it might give high score even if the result visually is weird. Tops I don’t remember exactly, but the turtleneck should give the least amount I think. Colors affect a bit too, but I honestly don’t even myself know how it works, just some weird equation with the rgb I made up.
The locks/cages not working can be a bug, they should work only if skirt and panties are see-trough.
Maximum should be this combination:
bare feet
see-trough nightgown
piercings
no bra
see-trough skirt
see-trough panties
cage
matching hair
some right color combination
