All hairstyles on all people men and women alike(I include transgenger as well cuz it applies to all people here) what hairstyles suit you really depend on your facial structure over anything else, that and head shape, some people look terrible bald, I know from experience that I do not, however with hair for me, my head shape and hairline makes me look good with short hair, or longer hair, but in different ways, and the in between lenth period looks horrible on me... I also can carry some facial hair styles better than others, and even though I have full growth coverage(I'm not patchy mcpatcherson) my facial structure lends a lot more to some styles than it does others, for instance, a goatee works, a moustache by itself... well unless it's full on hulk hogan style, it doesn't do me any favors, and even then I have to wear the right hat and the right clothing if I don't want to look ridiculous, whereas with a full beard, or a goatee with burns, or a goatee with burns and a jawline... line... I look good, however I don't think I could feasably rock a goatee, burns and a jawline... line with a bald head, i also look rediculous with no hair and no facial hair, if I'm bald I neeeeed to have a goatee, it's in my instruction manual.
So I can see why different women look good with different styles, some faces do not mix with short hair, some do, in fact I'd be willing to bet that most women with the correct style can sport either short or long hair given the correct ensemble, it's just that certain nuances in facial structure and overall form support one or the other more.
