We always had a nicely embroidered or lacy one for show or extreme emergency. Most guys wore them in the breast pockets of their suits and another in their trousers back pocket.
My grandmother always had a rose-scented hanky tucked away handily in her bra. In church, one of us would be sniffling and out would come the hanky to be applied to the offending nose.
Every time I smell rose sachet, I get a warm feeling thinking about how my grandma was always prepared for all contingencies....
