I don't think describing a common thought pattern has much to do with an increased sense of superiority. Have you never spoken about a behavior or activity that you think is bad? Were you exhibiting a superiority complex each time? Give me a break.
I don't feel the psychological effects of dressing well particularly strongly, but I acknowledge that others do and I don't think there's anything wrong with those feelings.
That's a very different position from being small minded enough to universalize one's own attitudes towards attire to "explain" the behavior of those who may not feel the same way as you. _That's_ what I was arguing against, the idea that virtue signalling must be the reason for putting less money and time into attire because people couldn't _possibly_ have different preferences.
Curious, were you wearing your higher quality clothing when you made this comment ?
For some, more expensive clothes increases their sense of superiority. I, for example, am less polite and less patient when I have to dress well. It isn't so much of a problem now that I am aware of it.
