In this article in Real Simple it talks about:

1. Staples
2. Statement pieces
3. Evening standards
4. Showstoppers

You also often see talk of “Spend” versus “Save” (or similar).

For me, my pyramid is:

1. Work – at home / School pick-up (mostly)
2. Work – meeting clients / going into office
3. Weekend – at home / shops / beach
4. Exercise – walking / gym / pool
5. Going out – friends bbq / out for dinner (rare!)

I’ve also seen pyramids that include – fashion pieces versus staples, accessories, coats.
