The only pattern to successfully outlive all turbulence in history of women’s hosiery, without losing its popularity, is the backseam. Sexual, not vulgar, it decorates legs like an exclamation mark, immediately attracting attention.
It even looks like some brands, like Gio or Cervin, carved out a special niche of customers who appreciate the traditional design of a fully-fashioned stocking.
Cosmetic backseam (just a straight line at the back) is relatively not hard to find if you live in a big city with plenty of department stores. But fully-fashioned stockings are a different story.
I personally have never seen fully-fashioned stockings for sale in any retail location. If it wouldn’t be for online hosiery stores, I would probably have no chance of getting my hands on one of those at all.
