How Short Is Too Short?

I know that this is a subjective question and that the answer will be different for everyone, but I`m just trying to get some feedback. I`m 25 years old and currently have an asymmetrical bob. I`m considering going really short with it next, though. I`ve seen a cut that I really like in a hair style magazine, but am a little worried about what people will think of it. The style is buzzed on the sides and back (not to the scalp, though) part way up - the rest is razor cut and blended with the top, which is short and spikey. It looks great on the model in the magazine and I look similar (petite, with small features), so I think it will work on me as well. What kind of reaction could I expect with hair that short? I know I shouldn`t care what people think, but it`s hard to disregard that completely. I`d just like to know what others might think and if they would automatically make judgments about me based on my hair.

Well, here in the good ol` South, it seems like people would prefer that their little Southern belles have the "traditional" big hair! I`ve been there and done that and now I think I`m ready to try the exact opposite! If I do it, I`m sure I`ll get some funny looks. I just hope it`s not something that people will just outright gawk at.
