However, they missed some obvious solutions that I know of from blind people, or my own quirks of having very different vision than human usual. These include:
* Put permanent labels in an inconspicuous place to identify features you can't see or remember. Blind people often do this with Braille but you can use any method that works such as hidden buttons. You may wish to label specific colors or a general class of colors such as warm/cool. This gives you much more independence in matching your clothes.
* Buy clothing that comes in sets, such as a sweater/blouse, top/bottom, or suit. Many designers also make batches of clothing meant to go together so you can mix and match a sweater, blouse, skirt, pants, and jacket all from that set.
* Closely related, use capsule wardrobes. This is nice if you want variety but have trouble matching things. You can't go wrong with the Whatever's Clean 13 template because everything in it matches. Consider, for example, having a warm and a cool set. Have someone help you make the set, store it together, and from there you can mix and match by yourself.
* If you have a favorite color, or you really don't care about clothes, consider wearing just one or a few colors. I have known several folks, not all of them vision-impaired, who did this for sake of simplicity. You can't mismatch your clothes if you own nothing that clashes.
* If you can't really appreciate colors, choose other features in your clothing to define your fashion. You might prefer to focus on the material, cut, or created texture such as knitting patterns.
