I think it's important that we don't cling to the rules our mothers taught us "just because that's the way it's always been done." If your legs look better with hose, wear hose. If you find that brown and black is not a good combination for your skin tone, then don't wear it. Don't be a slave to fashion rules -- old or new.
It always makes for an awkward moment when you've connected with a potential new client or business relationship over a cocktail and one of you fumbles for a business card that you never find. Have them easily available in business card holders or in side pockets of purses.
Save the makeup for the charity gala or Saturday night out on the town. The same can be said for perfume and cologne -- pick something that is lighter and more day-appropriate and don't overdo it. Just because you're so used to it that you can't smell it on yourself doesn't mean everyone else can't.
