Well I do not pay for any fancy powders, but down here we get pretty sweaty between the legs. And I mean running down your leg, under your breasts, down your back. and that is just walking out to the car some mornings.
So some women use it to help them stay dry. I put on panties and then spray deodorant all over my body in the summers.
We do this for brides and bridesmaid before they get dressed in bras and petticoats,.
Until you have experienced 100+ degree weather and + 60% humidity, none of that aisle will make any sense.
And Sometimes a vinegar douche is just needed. If you have not been airing out your privates enough. ie, sleeping with no underpants or pajamas at night is the best solution.
