I usually plan my outfits for the week at the weekend, hanging them up on my bedroom door complete with jewellery/ accessories (my wardrobe is in our corridor, so I can't do much outfit planning there lol)
When planning, I take a look at the remainder of the outfits hanging on my door & try to figure out why they're still there (usually weather was different than anticipated, or I'm trying not to throw things in the wash after one wear unless they need to be - e.g. underwear).
I then think about how I might incorporate these 'leftover' items for the next week. So I start with the clothes (lay each hanger on the bed) & then add underwear & accessories as needed. Often I'll keep an extra seasonal item hanging by them just in case (like a coat or scarf). I don't have a full length mirror in the bedroom unfortunately, so I either have to leave time to check the outfit in the hallway closet mirror before I leave (I bring a second hanging outfit with me in case I need to change) or factor that time in separately (once I have a whole outfit hanging, it makes it easier to bring that over to my closet & switch out whichever piece isn't working, rather than starting from scratch.
This process usually becomes much easier in the middle of a season (the weather is usually more stable by then).
