Type Of Style In Christina Aguilera Video "Candyman"?

Question

When she is in the diner with her girl dancers, and she has the rolled up capri jeans, with the button up shirt with sleeves rolled up and tied at the stomach, and the bandanas on the head with the pumps. What type of style is that called? I can't exactly pinpoint the era that it originated in. Please help me, because I REALLY want to pull off this look during the Summer. Also, can someone give me suggestions of where I could get the items for this outfit? And, what kind of accessories do you think that I should wear with this? Beads, bangles, etc.?
Thanks In Advance.
P.S. I know that I can get the bandanas at Claire's or a beauty supply shop. I want colorful button up shirts, not dull colored.

Looks like a modern version of Swing Style to me.

reminescent of the style during WWII
