My dress was a simple sleeveless cotton frock -- slim on top with a slightly empire-waist and a short but full-ish skirt. It was basic enough to allow for some accessory switcheroos along the way -- I wore ballet flats and a patent bow belt in the earlier part of the day and then switched to satin sandals and a jeweled waist-cincher for evening, which I had stashed in my (medium-sized) bag.
Unfortunately, I just attended another funeral and I was so relieved to have that same easy, no-brainer black dress to wear. Each one of my friends also had on superversatile frocks -- from a structured wrap dress to a form-sitting sheath. Coincidentally, my friend noted in her eulogy to her father, how his good pal Jackie Kennedy once told him how essential it is for a woman to have black dress and a houndstooth suit on hand.
After these experiences, I have really come to appreciate the beauty of the basic black dress. Now, I just need that houndstooth suit.
