My wardrobe super power is the ability to obscure the Tru amount of clothing I have using the same sort of accounting trickery that brought down the global economy in 2008. Like, I generally have so many garments in various stages of the laundry process that I have no idea how much crap I have.
This has come back to bite me in the arse on more than a few occasions. I'll notice that the garments needing to be ironed are overflowing the place I stick them until I'm feeling like ironing. This will cause me to say "well, if I'm going to iron clothes, I should probably wash the dirty stuff so I only break out the ironing board once"
I'll do all the laundry, iron all the clothes... Then, when I go to put them away, I realize that there is at least three or four times as many garments than I actually have storage space to hold.
So, I have no idea how to phrase it in a succinct and catchy way, but my wardrobe superpower is the ability to delude myself and the world into thinking I have a small wardrobe that actually fits into the microscopic storage I have for it.
