Yes, they do!
The state of my nails is usually sub-par. Not disgusting, just not as manicured as I'd like them to be. My hands are in the water a lot...)
However, well-fitted clothing, tasteful makeup (with sunscreen!), and groomed hair are a must. For now, I do touch up the greys.
Diamond studs (17th wedding anniversary present!), good watch (I bought for myself at age 40!) and wedding/engagement ring.
I've done jeans at work on Fridays, but colored ones or very dark. No frayed knees. Reasonable cut on the hipbones. Never leggings, unless under a dress.
And never sneakers. I will go to the ends of the Earth for comfortable ballet flats!
Do love Audrey Hepburn's style. Works very well for work at a school...
