This style looks somewhat like a partial updo with one side being swept up and pinned up in the back with the other side hangs down in a wavy bob.
If you looking for something a bit different for that party or special occasion, this one could fit the bill. It's edgy and different yet pretty and feminine. The long bangs are pulled over to the side and clipped into place with a decorative accessory. The waves are scrunched into place with fingers while drying with a diffuser. Here is a shot showing the pulled up side.
The event for this one is 50th Annual New York Film Festival – Opening Night Gala – "Life of Pi"
