This includes the selection, fitting and shaping of the hats You can determine who picks of the cost of the hat and embellishments. We can do an “Open Bar” where all the hats costs are covered by you. A “Partial Open Bar” which gives your guests a cost cap and anything above is their responsibility. Or, you can have your guests cover the cost of hats and embellishment.
