I had tried to find microfishnets locally rather than on-line and got nada. I did find Hue Micromesh that looks promising, but just a few stray pairs and none in my size so couldn't really examine. So I might order those on-line.

I do find a lot of patterned black hose, but all kind of large or bold patterns and this kind of fine pattern or something like a microdot. I was surprised.
