Ponytail, definitely, IMHO!!

While I love contemplating a shiny, voluminous, intricately woven bun, I still think Big Bopper said it best:

"Chantilly lace and a pretty face,

a pony tail, hangin' down...

... makes the world go 'round"

I absolutely love walking behind a woman with a long, straight silky tail of hair, watching it swing and bounce and glide back and forth across her shoulders, back, and (hopefully) hips as she walks, gleaming and dancing with every move of her head. A beautiful sight to behold, always!!!
