IMHO, there's nothing wrong with a ponytail! Regardless of what shape your face is. I do think there could be a difference in how you wear the ponytail as to whether or not it compliments your face shape.
I think ponytails pulled back with scrunchies are a no-no, but if they're secured with those Ouchless bands, a ribbon, or with a piece of your own hair wrapped around it and bobby pinned, then it can be pretty and trendy. /emoticons/[email protected] 2x" width="20" height="20" />
And I have an oval face and I wear my hair back, either in a pony tail, a clip or with bobby pins. Do what makes you comfortable. /emoticons/[email protected] 2x" width="20" height="20" />
