IMHO and respecting all your tastes, for me, waist length is the best and ideal length.

Why? 'cause is the limit of get a normal life for a long hair girl. More long is uncomfortable, and the ends are full of breakages and is thin and old hair. Usually these girls are always with her hair hidden, 'cause if they don't protect her hair it will be ruined.

Waist length is long hair for sure, but it's still comfortable and can be sported loose everyday and maintaining the health and thickness intact. Knee and even floor length is not beauty IMO.

For me is because my taste is more thick hair than long hair... but this forum is Long Hair Forum and I respect all of you, but for me the thickness and health is the key of beautyness.

And for me, the perfect hair is Alexandra Arriaga's hair... she has the perfect mix of genes (spanish, and latin), perfect colour, and she's also an expert in bio chemicals and helps other girls to care her hair. My goddess.
