trust me, it looks really cute. I did the same thing last year (my hair was about the same length as yours) and HATED it after I cut it off. I think it just takes some getting used to. It makes you look funky chic.
i love it, i think it makes you look older, and its true, it grows back lol!it doesnt take long!and try and do your hair different ways, use some different products and stuff so that you can make it look a little versatile untill u get some length back.
i felt the same way when i had my hair chopped off, but now i think it looks "finished". whereas before it was just long red hair that i ould have up or down, and that was it, now i can style it and spike it up, and i love it.
you really do look good with short hair hun, and if you really dont like it, grow it again, and it'll be in better condition too!
