Back in the late sixties, I was in charge of a department of a large bank located in a huge building in El Monte which, as most Southern Californians know is not the fashion capitol of the world. One morning my secretary asked me if it would be all right to wear a pants suit to work. Sure, says I especially since we're still unpacking boxes. In fact, for a couple of days, why don't you just come in in jeans. Two days later, I got a call from head office in San Francisco.
Women wear skirts and blouses, a suit, scarves, that sort of thing.
We considered uniforms that even the airlines wouldn't allow. It's not the way we do things around here, and we haven't done them that way for a hundred years. Women wearing pants does no harm, and if it makes women more comfortable, so much the better. We've got men representing the bank who wear the most gawdawful garb, ties wide enough so that they don't have to wear shirts, knit trousers with bellbottoms, and hair that's shoulderlength. Our dress code calls for skirts and blouses or suits.
