Being a natural "emotional dresser'', it was always what I felt like the day of.
The problem was, this method too often gave way to ''Nothing-To-Wear-Change-5-times'' mornings, which I absolutely detest.
I tried to become a planner. And tried. But it just doesn't work with me. At night, when I finally have a minute to myself before going to bed, I have no inspiration whatsoever to start pulling out clothes and decide on outfits.
So my solution: I became a planned-emotional dresser. Every two-three days, I select in advance a couple of tops, bottoms, dresses, and jewelry that go together. I place them at the front of my wardrobe. I do this anytime during the day, here and there, add, retrieve something.
Then I choose between these and only these in the morning. I found this method satisfied my desire to dress as I felt in the morning, while taking away the guilt of not wearing some items (because a small selection has been made), or the guilt that I would be wearing the same things (because again, the selection is small)... the result is more freedom, believe it or not, and drastic decrease in fussy mornings. And who cares if I end up wearing almost identical outfits two days in a row? Nobody really notices, or if they do, they don't really care. If it makes me happy...
I guess this is one step away from a daily planned outfit.
