I agree with sam.Sure marianne's hair is fine but in case of marin the texture of the hair as seen in most photos is not suitable for that length.I also agree that mid back/butt length with volume and life is better that ankle/knee length and staggly.Moreover butt length hair attracts a different kind of attention if its full of life.But very long/ straggly hair also gives rise to a kind of "oh she can't maintain her hair/she attractive if her hair was slightly shorter attitude". I would also like to see the opinion on of our hair board veterans here.
