A Sagittarius man may prefer a woman who has something she can devote herself to. He is likely to be drawn to a woman who is focused on work or hobbies without worrying about her appearance, rather than someone who wears fashionable clothes and is well made up. He seems to find a unique charm in the expression of passion and joy when talking about something he is passionate about.
Furthermore, Sagittarius men feel a sense of sexiness in lively and healthy appearances, so they may feel excited when they see women who move lightly. Even in fashions that are far from sexy, such as pants looks and casual outfits, they seem to think that women who freely enjoy clothes that suit them are appealing.
