I have around 14 pairs of tights, pantyhose. A mixture of various deniers.
A couple of pantyhose are thick, 200 denier, which I only wear in winter. They are more like tights, but I include them as pantyhose because they have the feet part.
I have some more sheer pantyhose, all in black.
And I have a mixture of tights, in blue, and black. Full leg, and 1/2 calf. And in medium and large size.
14 is a good round number, as we do a fortnightly laundry run.
I did raid a pair the other night, as we have moisture in the cupboards. I cut the feet off and filled them with rice. When the pantyhose breakdown, we cut them into strips and use them in the garden, as stake ties..
