I don't arrange wardrobe into outfits but do have everything similar together so all blouses, short sleeved tops etc, then jewellery in different boxes, big chunky ones, delicate ones, bangles, cuffs etc. then I find it easier once I've decided on one item (usually the bottom half) to sail through the wardrobe picking bits that go with it. Bog standard I guess, would be interested to hear if anyone groups wardrobe items into outfits. Will watch with interest!!
All light tops together sectioned into colours. Same for jumpers. Trousers all together on hangers. Jeans rolled up like towels. Shoes in shoe hangers from TK Maxx Scarves all in a basket on top of the wardrobe. Leave out underwear, tight, socks, the night before. No actual outfits chosen but everything easily seen and accessed.
Spend an afternoon in front of the mirror figuring what goes with what.
The key is to shop in outfits - ie I don't buy a top if I don't know what bottom I'd wear it with - either something I already own or something I can buy at the same time to wear with it.
Then colour code your clothes - eg most of my autumn winter separates and dresses, tights, belts, scarves, necklaces go with each other - mix and match. Then I have print dresses with different colours on, which may not go with other stuff, but have their own tights, shoes, jewellery to create an outfit.
