In my bedroom closet I arrange in order from the left:
suits, catsuits, long dresses, mid-length, mini dresses, long skirts, mid, knee, mini, pants, the skimpiest through the most substantial of camis that have to be hung up (so nothing knit, as that would stretch,) increasingly substantial camis to tank tops, sleeveless shirts, tshirts, long sleeve shirts, button down shirts.
Then on the shelves above this I have in order from the left:
cardigans, zip-fronts, misc front opening sweater type things, tops and sweaters that do not open but are typically worn over other shirts, purses
below I have shoes in boxes, but only the out of season or rarely worn shoes.
I also have two wardrobes, two high-boys, and a dresser. I'm fanatical about which drawers are for what. And for those things that I probably will never wear again, but I can't bring myself to donate just yet, I have boxes in the attic.
