i love my hair in a bob. i'm growing it out from a chin length inverted cut (shorter in the back graduated to longer in the front, in an angle as the poster above described).
right now it still has that same shape, but the front is almost shoulder length.
i absolutely love this cut. nothing has ever been easier to take care of or looked as good on me. it's me 'default' cut, and the one i always come back to.
edit: i'll add some pics of my bob cuts to my yahoo albums.
coarse, thick 3a
