Thak you @suntree happy new year, I am not sure to be honest I have seen all age groups dress up as Santa from young children to the elderly. Good point you don't see as often an old lady dress up as Santa but I feel this is just more of an age thing, in general the younger crowed prefer to dress up in costumes rather than the elderly. Same here I dont see what they would gain out of it except mostly lose money for a joke they wont witness.
