Hair up. But I would smooth it out and curl the little tendrils so it doesn't look haphazardly put up. I love what you've got going on in these pics but I think itd look more professional if it were more "purposeful" looking. Does that make sense?
That said. I just did my own first Phost. I'm trying to decide which dress to wear to my SIL wedding tomorrow. I'm not getting definitive answers, meaning no real consensus. Would you mind taking a look? http://ebullientjenn.livejournal.com/177571.html
