How can I put my hair up without looking like a witch?

[lucysnowe]

I am growing my hair hurray! but as I am pushing forty all the cool ways to put it up that you see on pinterest, involving elaborate braids, buns etc, would make me look like a scary old witch and/or mutton dressed as lamb. Are there any styles which are a bit more elegant/timeless (besides just shoving it into a ponytail)?
