I need a little help, probably mostly from the ladies on this one.  I'm watching this video by this singer named Rachel Platten called "Fight Song". The tune is really popular right now in the US, but that's not what I need help with. Near tyhe end of the video, Rachel is walking along the beach while wearing this long flowing white skirt (dress?) Anyway, I want to make a dynamic version of thedress for Roxie, but I can't get a really good look at the dress in the video. Can someone tell me what the name of that dress is, so I can look it up and get a good look at it?

If you haven't seen the video, the Youtube link is : Fight Song by Rachel Platten
