These adorable hats are as light as a feather, and attach to a black plastic hair band that is comfortable and not too tight.  Easy to slide from side to center for whatever style of wear you chose.  Black wool felt is the basic first choice, the other choices are the same hat with either matte and shiny black cloth roses, or roses and feathers.  For easy wear, make a small nub or bun with a little of your hair to go underneath the hat and it will always stay in place.
