Rosie the Riveter is to this day considered a feminist icon in the United States. Today, the term wearing a bandana or scarf "Rosie style" refers to having the center of the bandana at the base of your neck ending up with the knot at the front of your head where a normal headband would be. This is how "Rosie" wore it in this World War II "We Can Do It" poster. The woman in the poster is commonly mistaken for Rosie the Riveter but she isn't. But for fashion's sake, let's just say she is.
I like a wide fold for my bandana, but it's definitely a personal preference. There are some variations on how to tie it as well. They all start off with a standard bandana folded into a triangle. You can either keep it like that or you can take it a step further like I did and fold it. I simply took the point of the triangle and folded it the opposite end and folded it in half one more time.
I did some variations on my bangs as well. First, I simply took a big barrel curling iron and curled the front in. I got a pretty big "rockabilly" curl. . . . Next, I rolled the big curl around my finger and pinned that to make a pin curl. Finally, just for kicks, I took the pin out and got a tighter curl than the curling iron did on its own.
