Hiya Papaya! I 100% don't have a type.
Here's what costumes work(more or less)
School Uniform: psgkneesocks, demon_uniform, necktie, glasses
Swimsuit: psgkneesocks, demon_swimsuit
Demon outfit: demon_outfit, bra, glasses, skirt, thighhighs
The demon outfit is the hardest to get right especially if you want to wings. Might retrain for better wings if I decided to revisit this. Also fun fact, despite being named Kneesocks she actually wears over the kneesocks/thigh-highs.
Helpful terms: single_horn, glasses
