Hair Help

I am attending a wedding of a very dear friend in about 10 days and I'm quite literally counting down the minutes. The only minor problem is that I will be getting ready by myself.

For those that know me know that I wear my hair straight and down probably 360 days of the year. Hair just isn't my thing, but in an attempt to be classy for Caroline's wedding, I need major hair help.

UP?

 Or DOWN?

All suggestions welcome!
