My decision to join an amateur vocal chorus means I have had
to add to my wardrobe, what are called "concert blacks".
Black blouse, full-length black skirt, black shoes.

My big de-clutter is high heels: no more, never again.
Sure, I have some shoes/boots with one-inch heels, but that's not high.
And the black shoes have to be decorous-looking onstage,
so they have to be nice shoes;
but they can still have lower heels and be acceptable.
