As far as ocd things go, it's not a big deal imo. In my experience throughout my life my personal flavor of ocd gets worse when there are things I am trying to avoid thinking about.
When I was a young teenager there was one girl who had so many clothes. Always had the latest things, multiple versions of what had just gotten popular. A friend remarked about being jealous, but to me, at that time I also thought it was kind of "rude" somehow to the clothing items to not care about them, to wear an outfit once etc. I also found early on that to me the most fun about fashion is putting things together in different ways, appreciating the items.
Unrelated, but at one point I found out that the girl with all the outfits had 2 or 3 sisters, they were all close in age/same size and they all shared, so that in some ways was better, but worse, for the clothes, just being passed around. LOL
