I've been there and done that, mainly due to a lack of concentration I've often wandered off in the wrong direction, I hate it when I do this!
In my early long distance walking days I made the mistake of carrying three baselayers, three underwear, three pairs of socks and when I bought them they were all of the same colour, make and model. My plan was to rotate each day, wear 1, wash 2, dry 3. Didn't work, I got in such a muddle I forgot which one I wore first and wore last, which one I needed to and so on.
It got to the point where my humiliation was to smell the fabric to know which was which!
I no longer carry three items, now only two of each. Wear 1, wash 2 and dry, wear 2, wash 1 and dry, then back to the start. It just needs a bit of discipline on my part and for me it works well. I also now try to buy different colours, much easier to manage. If not I just sew a white thread 'A' and 'B' on each item so I know which is which.
