A true joy of neurdivergent adulthood:

Buying the exact same garment in more than one color.

As multiple people are asking:

Whether this related to ND depends on why one is doing it. If you buy multiple versions of the same thing because you genuinely don't care what you wear, it's not necessarily ND at work.

If, on the other hand, it's that one kind of garment is especially good (especially from a sensory standpoint), or that one is easily overwhelmed by choice, or that one really loves predictability, well, ND may well be a factor.

For me, and this particular pullover, it's both a sensory thing in multiple ways, but also it's a very practical garment for my needs.

You do you, regardless of the reason why!

Turns out I have another note:

When I use the word "joy" here, I do so with the context of other writing about it, including, fundamentally, this from @JustStimming https://juststimming.wordpress.com/2011/04/05/the-obsessive-joy-of-autism/

For me, this is not just about how this pullover is good, or about how I have created a life where a duplicate item won't invite ridicule.

Although those things are good!

For me, this is about a deep sense of satisfaction and joy. I am doing exactly the right thing for myself. I am inside this garment that is so good, and I love it so much, and I have TWO, and things like the thumbholes fill me with a deep contentedness.

And sharing this, for me, isn't so much about "how easy it is to pick an outfit" (although, if that's a thing for you, I appreciate it for you!).

For me, this is about sharing a JOY that offsets some of the difficulties in ND life.
