The 30s saw many tight to the head hats including the beret!
Oh, yummy!
The 40s saw the beret move to sitting on the top of the heat at a jaunty angle.
So chic!
Berets can be decorated with a pin or feather.
While black is a classic beret color don't neglect other colors or even patterned berets! Also knit and crocheted berets were popular.
