This is easily obtained by chopping off long hair. It looks good on most girls (pixie is harder to pull off) and can be styled in millions of different ways. Its easier to maintain so its a win-win situation. Girls with shorter hair are not lesbians (although I speak only for myself). Emo girls will dye their short hair bright colors, prep girls might curl theirs, and rocker chicks will give theirs a choppy,layered look. Short hair is super versatile.
Although I cut my hair short and layered, I am as straight as they come :).
WARNING: If you plan on flirting, seducing, or hooking up with guys, I suggest long hair because men tend to like that type more (although I have proof that boys like short hair too).
