Super fun and cute, especially for warm weather, no? You definitely don't have to do as many (or make a Mohawk) as they showed at Marc by Marc Jacobs, but keep these elements: the sticky-outty ends and the tightness of the coils.
Even if you've got a bend to your hair/so much of it one puny clip could never hold it all, you can still adapt this hyper-polished Guy Laroche pony. Pull the top section back with one of these guys, or take a few barrettes and secure the hair horizontally halfway down. The juxtaposition of a slicked-down front and an explosion of natural texture in the back is just as chic.
