What's the one clothing item you can never find?

I’ve had so many fashion pieces I’ve wanted over the years, but have had absolutely no luck finding them. They either don’t fit right, cost a fortune, or are made of some godawful material.

One example is a simple black turtleneck. I want a tight fit, something that doesn’t hang like a bag around my waist, with a neck that doesn’t slowly give up and slide down. The black needs to be actually black not some washed out grey/black identity crisis. No polyester-microplastic-recycled sewage mystery blend and ideally something that doesn’t require me to mortgage my house. I cannot find this friggin thing anywhere. Is it too much to ask? Apparently.

Do yall have an impossible to find clothing item? What is it?
