I have shoulder length hair, never had it shorter,i am thinking about geting a kind of bob haircut,

Go for it!

Hair always grows back. Make sure it's an easy to manage hairstyle - diving into a tough hairstyle for your first time isin't smart (said from expirience)

So until you know how to manage short hair, go for a cute and easy bob and you'll be fine. [:

Well for one thing it mostly depends on the shape of your face.

if you have a narrow or heart shaped, oval shaped face then yes it will probly look good but if you have a circle shaped face then that's not a good idea.

Because if you get a bob-type hair cut and you have a circle shaped face then your face will then look shorter and chubby.

And nobody wants that.

But if you do decide to go with it, don't just get the plain jane bob.

spice it up add texture and a little color and you wont be sorry.
