The more detailed the better. Although I do understand some people aren't as particular with their tastes as others
For me my perfect woman is a woman around 5'2, chubby and curvy, Asian with dark skin for her physical features.
Personality, I like someone who is bubbly, gentle, a bit on the quiet side, playful and very affectionate. Weirdly enough I also find it so attractive when a woman presents herself visually in a very girly manner but her mannerism are a bit tomboyish (openly burping, cursing a lot, eats well, enjoys inapproriate jokes, etc.)
